What Happened in HVAC in 2025 — 20 Key Developments

1. The Refrigerant Phase-Out Takes Effect — R-410A Out, A2L Refrigerants In

On January 1, 2025, the U.S. regulatory environment shifted dramatically for HVAC systems. Under the framework of the Environmental Protection Agency (EPA) and the American Innovation and Manufacturing Act (AIM Act), manufacturing of HVAC equipment using high-Global Warming Potential (GWP) refrigerants — notably R-410A — was phased out. New systems now must use lower-GWP refrigerants such as R-454B or R-32. ACIQ+2Riteway AC+2
This shift aims to reduce the environmental footprint of HVAC systems, but it also introduced challenges: supply shortages for A2L-rated refrigerants, increased equipment prices due to added safety and compliance requirements, and a steep learning curve for contractors that must become certified in new refrigerant handling protocols. HVAC Informed+2ACHR News+2

Other key impacts: older systems using R-410A remain serviceable, but long-term maintenance is likely to grow more expensive, and new installs in 2025 and beyond will bear the burden of compliance. Superior CO-OP HVAC+1

2. The Rise of Heat Pumps and Electrified HVAC — “Electric is the Future”

One of the major themes of 2025 was accelerated adoption of heat pump technology. Heat pumps — especially advanced systems capable of operating efficiently even in cold climates — made big gains in both residential and commercial sectors. HVAC Informed+2Building Decarbonization Coalition+2

The drive toward electrification reflects broader decarbonization goals. For many building owners and facility managers, switching from fossil-fuel-based furnaces or boilers to all-electric heat pump solutions meant long-term energy savings, reduced carbon footprint, and compliance with emerging efficiency and environmental standards. Building Decarbonization Coalition+2Merlin Monitor+2

As climate policy and incentives from governments push toward cleaner energy, heat pumps are increasingly seen not as a niche alternative, but as the default for new HVAC installs or major retrofits. ACHR News+1

3. The 2025 AHR Expo: Industry’s Big Showcase for Change

In February 2025, the AHR Expo (held in Orlando) served as a major inflection point — showing where the HVACR market is headed. Attendance was strong (50,807 participants), and hundreds of exhibitors displayed the latest in equipment, controls, refrigerants, and smart automation. ACHR News+2Avnan+2

Key themes at the show included: transition to A2L refrigerants, proliferation of smart/IoT-enabled HVAC equipment, rising demand for high-efficiency systems, and increased emphasis on sustainability and decarbonization. ACHR News+2HVAC Informed+2

For many contractors and building owners, AHR Expo 2025 underscored that changes already underway — in regulation, product design, and market demand — are not temporary: they represent a new baseline for the entire industry. Avnan+1

4. Efficiency Standards Tighten — New DOE/EPA Rules on SEER, HSPF and More

In 2025, minimum efficiency requirements for HVAC equipment got more demanding. Compliance with upgraded standards for cooling (SEER/SEER2), heating (HSPF2), and overall fuel utilization (AFUE) became more widespread, pushing manufacturers to produce more efficient and greener systems. Northstar HVAC/R+2Mar-Hy Distributors+2

For building owners with older HVAC systems, this raised the cost-benefit bar for replacement vs. maintenance. For new installations, it meant choosing systems designed for long-term energy savings — and possibly qualifying for incentives or rebates tied to efficiency and environmental performance. Northstar HVAC/R+1

5. Smart & AI-Driven HVAC Control Gains Traction

2025 saw increased interest in integrating AI, IoT, and data-driven controls into HVAC systems. One recent academic study, for example, proposed a “Human-in-the-Loop” (HITL) framework that adapts HVAC operation based on real-time user feedback and changing electricity market prices — improving comfort while reducing energy costs. arXiv+1

Meanwhile, other studies focused on advanced ventilation and air-quality control: a data-driven operator learning model showed how machine-learning + ventilation controls can optimize airflow and maintain indoor air quality while minimizing energy use. arXiv

The result: HVAC is no longer “set it and forget it.” Smart, responsive controls are becoming a core part of system design — especially for larger or multi-zone buildings. HVAC Informed+1

6. Widespread Adoption of VRF & Hybrid VRF Systems in Commercial Settings

Variable Refrigerant Flow (VRF) systems — long favored in niche commercial projects — saw a surge in 2025 adoption. The shift is driven by their flexibility, efficiency, and suitability for buildings needing simultaneous heating and cooling, or varied climate zones (e.g., offices, hotels, schools). Merlin Monitor+2HVAC Informed+2

Hybrid VRF systems (some combining refrigerant with water-based distribution) also gained traction, particularly in retrofit projects replacing legacy chillers or boilers. These hybrid systems offer decarbonization potential while lowering operational expenses. HVAC Informed+1

As more building owners look to reduce emissions and energy costs, VRF — once a “premium” option — is becoming mainstream. ACHR News+1

7. Market Disruptions: Refrigerant Shortages, Pricing Challenges, Supply-Chain Strain

The transition to A2L refrigerants wasn’t smooth. Many contractors and distributors reported supply shortages, difficulty procuring sufficient refrigerant for new installs, and delays in project timelines. ACIQ+2HVAC Informed+2

The result: some homeowners and building managers postponed HVAC upgrades or chose to stick with older R-410A systems (while still possible), creating a temporary “two-speed” market. Others opted for alternative solutions — like heat pumps, VRF, or heat-pump water heaters — that avoid refrigerant supply constraints altogether. Harvest Thermal+2Merlin Monitor+2

8. Increased Demand for Training & Workforce — Technicians Need New Skills Fast

With the new refrigerants, heat-pump systems, VRF technology, and smart/AI-driven controls, the skill set required of HVAC professionals expanded rapidly in 2025. Contractors must now be certified in handling A2L refrigerants, familiar with modern heat-pump installation and maintenance procedures, and capable of commissioning smart control systems. HVAC Informed+2Mar-Hy Distributors+2

This has exacerbated an existing labor shortage in HVAC, but also opened opportunities for training, specialization, and higher-value services. For many smaller HVAC firms, the transition represents a strategic inflection point — adapt or risk being left behind. Mar-Hy Distributors+1

9. Air-to-Water Heat Pumps & Thermal Storage Gain Ground — Toward Electrified HVAC for Heating Season

This year brought broader adoption of air-to-water heat pump (AWHP) systems, especially in colder climates or where building plumbing is compatible. AWHPs offer a flexible, all-electric alternative to boilers, often with better efficiency and easier integration in retrofit and new-build projects. Harvest Thermal+1

In many cases, AWHPs were being specified alongside thermal storage solutions — for example, using heat-pump water heaters (HPWHs) controlled with predictive algorithms to store hot water or heat during low energy-cost periods. Early field studies showed promising energy savings using model-predictive control (MPC) for HPWHs. arXiv+1

For building owners and developers focused on decarbonization and resilience, AWHP + thermal storage began to look like a “future-proof” heating and hot-water solution in 2025.

10. Smart HVAC Controls & Zoning Surge — Targeted Comfort, Lower Energy Use

Multi-zone HVAC control got a real boost in 2025. With rising energy costs, upgraded refrigerant mandates, and more homes/buildings requiring flexible comfort control, zoning systems gained traction — especially those that are easy to install, compatible with existing equipment, and can integrate with smart thermostats. ZoningSupply.com - Zone Control+2Ecology Jay+2

On that front, Ecojay’s release of SmartZone-4X 3.0 and SmartZone-3X 3.0 marked a notable milestone. The new 2025 controllers offer universal compatibility (gas, electric, heat pump, dual fuel, etc.), support for up to 20 zones (expandable), built-in fresh-air and economizer controls, de-humidification/de-humid modes, and configurable multi-stage control — all in a controller that installs far more simply than many legacy zone boards. Ecojay Products

The “3.0” update includes an improved bright color display, LED diagnostics on every terminal, fresh-air intake and humidity/economizer options — making zoning more accessible and practical for retrofits and new builds alike. EcoJay Products

For many homeowners and smaller commercial buildings that struggled with temperature imbalance, variable occupancy, or ductless HVAC discomfort — zoning with modern controllers became a go-to solution in 2025. As one distributor summary put it: for many applications, SmartZone 4X (or 3X) is the “clear winner” for universal compatibility, ease of install, and long-term reliability. ZoningSupply.com - Zone Control

11. Adoption of Smart Zoning & Dampers — Precision Airflow Control Comes of Age

Beyond just zone controllers, 2025 also saw growing interest in integrating smart dampers and automated airflow controls in HVAC systems. This allows for even finer-grained control: each zone’s airflow can be adjusted not just by thermostats, but by damper status, supply-air sensors, and system logic responding to occupancy, air quality, or humidity. EcoJay SmartZone Spec

When combined with Ecojay’s SmartZone 3.0 / 4X 3.0 platforms, these systems can offer multi-zone control, fresh air ventilation, economy modes, staged heating/cooling, and dehumidification — all with a relatively simple, retrofit-friendly install.

This trend — toward airflow optimization rather than “one-size-fits-all” heating/cooling — reflects a broader shift in HVAC: from brute-force temperature control to intelligent, adaptive comfort systems.

12. Smart / AI-Powered Building HVAC Controls — From Theory to Real Deployments

Several research efforts published in 2025 pushed HVAC control past fixed schedules and static algorithms: machine-learning, occupancy detection, predictive control, and feedback-driven comfort management moved from labs into real-world simulation and field-test phases. arXiv+2arXiv+2

For example, one “Human-in-the-Loop” (HITL) model dynamically adapts HVAC operation based on user feedback and changing electricity prices, improving comfort while reducing energy consumption. arXiv

Another framework used neural-operator learning to optimize ventilation airflow and vent angles, offering substantial energy savings while maintaining indoor air quality. arXiv

As smart building technology becomes more common, these approaches could reshape how HVAC systems are designed, installed, and operated — especially in larger residential complexes, offices, or other multi-occupancy buildings.

13. Security & Privacy Research — HVAC Systems as Attack Surfaces

2025 wasn’t all about efficiency and comfort — researchers also flagged emerging risks tied to the increasing complexity and connectivity of HVAC systems. One academic paper introduced a framework for detecting cyber-physical attacks on HVAC components (sensors, actuators, networked controllers), using machine-learning to catch anomalies while preserving privacy. arXiv

Even more startling: another study demonstrated that common HVAC pressure sensors can be used to reconstruct intelligible human speech — meaning that HVAC systems might inadvertently become privacy or eavesdropping vulnerabilities. arXiv+1

These findings introduced a new set of concerns for building owners and managers: as HVAC becomes smarter and more connected, security and privacy need to become part of the spec.

14. Thermal Storage + Heat-Pump Water Heaters — A New Combo for Efficient Heating & Hot Water

Leveraging smart control and predictive algorithms, heat-pump water heaters (HPWH) paired with thermal storage — once thought of as a premium add-on — began to emerge as a viable, practical solution for many homes and multifamily buildings. A recent field study showed that a 120 V HPWH managed by a model-predictive control (MPC) system could pre-heat water ahead of demand, reduce energy costs by ~23–28%, and slash energy waste compared to traditional systems. arXiv

For developers and retrofit specialists, the appeal is clear: combined with A2L-compliant heat pumps or all-electric HVAC systems, thermal storage + HPWH offers low-carbon, efficient heating and hot-water — and reduced dependence on gas or fossil fuel systems going forward.

15. Retrofits & Upgrades Surge — Aging Systems, New Standards, and High Demand

Faced with new refrigerant regulations, rising energy costs, and pressure to decarbonize, many homeowners and building owners opted in 2025 to upgrade or retrofit older HVAC systems rather than continue band-aid repairs. This included replacing older R-410A systems, installing all-electric heat pumps, adding zoning boards and dampers, or integrating smart controls for better efficiency.

Contractors and distributors reported a spike in remodel and retrofit requests — especially from clients seeking to bring older systems into compliance or improve comfort in older homes and small commercial buildings. ACHR News+2HVAC Informed+2

These trends signal that 2025 — more than a regulatory transition year — may be a peak moment for modernizing America’s HVAC stock.

16. Renewable & Geothermal HVAC Solutions Gain More Attention

As decarbonization momentum grew, the industry saw renewed interest in geothermal heating/cooling, solar-assisted HVAC, and other renewable-energy–integrated solutions. Contractors and stakeholders began to position these technologies not just as “green” options, but as viable long-term alternatives, especially where clients wanted to minimize reliance on fossil fuels. PR Newswire+2Northstar HVAC/R+2

In some jurisdictions, this trend dovetailed with incentives and regulatory pressure — a combination likely to accelerate adoption in the next few years.

17. Awareness of Indoor Air Quality (IAQ) & Fresh-Air Ventilation — Zoning Controllers Adapt

With increased focus on occupant health and building resilience post-pandemic, IAQ became more than just a “nice-to-have” topic. In 2025, many new HVAC products and controls emphasized built-in fresh-air intake, economizer modes, humidity control, and ventilation compliance with standards such as ASHRAE 62.2. EcoJay SmartZone SPEC

Zone control panels like Ecojay’s new SmartZone 3.0 / 4X 3.0 integrate fresh-air and economizer capabilities — making IAQ-focused ventilation part of the standard zoning package. Ecojay+2

For schools, multifamily residential, and commercial buildings, this shift underscored that HVAC isn’t just about comfort — it’s increasingly seen as a core element of occupant health, safety, and resilience.

18. Demand Surge & Backlogs — HVAC Supply Chain Under Pressure

Between refrigerant shortages, increased demand for heat pumps, and widespread retrofits, many HVAC contractors and distributors in 2025 found themselves with long lead times, backlogged installs, and stretched supply chains. Several reports pointed to delays in components, refrigerant cylinder shortages, and pressure on inventory of compliant equipment. ACIQ+2HVAC Informed+2

This environment drove up installation costs and wait times for homeowners — but also created opportunity for well-prepared contractors who secured materials early, invested in training, and offered bundled retrofit/zoning/upgrade services.

19. Growing Momentum for Building Electrification & Decarbonization — Regulatory & Market Forces Align

2025 felt like a turning point for building electrification. Regulatory pressure, incentives, public concern about emissions, and rising gas prices pushed more property owners to consider electrified HVAC, heat-pump water heaters, geothermal, solar-assist, and other low-carbon solutions. PR Newswire+2Merlin Monitor+2

As a result, HVAC design conversations began to shift. Rather than specifying “gas furnace plus A/C,” many architects, MEP engineers, and contractors started designing buildings from the ground up for electric heat — often with zoning, smart control, and renewable integration in mind.

20. Zoning & Damper-Based HVAC Control Comes Into Its Own — SmartZone 3.0 Leading the Way

One of the most notable developments in 2025 was the renewed focus on zoning and airflow control — especially for residential and light-commercial buildings. At the center of this movement was Ecojay’s release of SmartZone 3.0 (both 3-zone and 4-zone / multi-zone versions). Their new controllers — the SmartZone-3X 3.0 and SmartZone-4X 3.0 — combine universal compatibility (gas, electric, heat pump, etc.), support for up to 20 zones (expandable), built-in fresh-air and economizer controls, dehumidification modes, multi-stage staging controls, and a modern LED/status interface. EcoJay

For many homeowners, this meant zoning was no longer a niche luxury — it became an affordable, retrofit-friendly way to improve comfort, reduce energy waste, and manage airflow intelligently. According to distributors, SmartZone 4X 3.0 emerged as the “best overall” option for larger homes or light-commercial setups, while SmartZone 3X 3.0 offered strong value for mid-sized projects. ZoningSupply.com - Zone Control

For contractors, the simplicity of installation — screwless terminals, dip-switch configuration, built-in supply-air sensor, and LED diagnostic feedback — helped reduce install time and complexity, making zoning a more attractive upsell or retrofit option. ecojay.com

Overall, 2025 may have marked the moment when zoning and damper-based control finally became “mainstream” in HVAC — not just for luxury homes, but for ordinary homes and small commercial buildings too.

Looking Back — What 2025 Means for the Future of HVAC

2025 was a watershed year. The combination of environmental regulation (phasing out high-GWP refrigerants), rising energy / carbon awareness, technological advances (heat pumps, smart controls, AI, zoning), and shifting market dynamics (retrofitting, supply strain, demand surge) forced the HVAC industry — contractors, manufacturers, building owners — to adapt quickly.

What stands out is that many of these changes point to a longer-term transformation: from HVAC as a commodity “cooling/heating box,” to HVAC as an integrated, efficient, adaptive, and even healthy system — delivering comfort, air quality, energy efficiency, and environmental responsibility.

The rise of smart zoning (e.g., Ecojay SmartZone 3.0), air-to-water heat pumps, thermal storage, AI-driven controls, and electrified systems suggest that “HVAC 2025” is really “HVAC 2035.”

If you’re a homeowner, building manager, or HVAC professional — 2025 was more than a transition year. It was the start of a new era.

Understanding ECO / Away Mode on Ecojay SmartZone Controllers

What It Does, How It Works, and When to Use It (SmartZone-3X, SmartZone-4X, and with SmartLINK)

Ecojay’s SmartZone zoning controllers include a unique feature called ECO / Away Mode. Unlike energy-saving modes on thermostats or variable-speed systems, ECO Mode on SmartZone is specifically designed to control which zones are allowed to make equipment calls.

This article explains exactly what ECO/Away Mode does, how it affects damper operation, how to wire/activate it, and how it works in multi-board SmartLINK systems.

➡️ SmartZone Installation Guide: https://zoningsupply.com/smartzone34x-guide
➡️ View ECO Mode switch Product Page: https://zoningsupply.com/buy/eco-away-mode-switch

⭐ What ECO / Away Mode Actually Does

When ECO/Away Mode is active, SmartZone changes how heating or cooling is allowed to start:

✔ Only Zone 1 can energize heating or cooling equipment calls.

Zone 1 becomes the only thermostat that can initiate a call for heat or cool from the HVAC system.

✔ All other zones behave differently:

• If another zone is calling for the same mode (heat or cool),
  → its damper opens, but it cannot start the equipment.

• If a zone is already satisfied,
  → its damper stays closed.

• If all zone thermostats are satisfied,
  → all dampers open (normal SmartZone behavior).

ECO Mode does not change staging, delays, fan logic, or temperature thresholds.
It simply controls which thermostats can and cannot call for equipment.

This makes it extremely useful for vacation homes, commercial buildings, sleeping areas, or any application where you want the system to run only when Zone 1 wants it, while still allowing or preventing airflow to other zones.

🔧 How to Activate ECO / Away Mode

ECO/Away Mode can be activated using:

• A wall switch

• A relay / thermostat output

• A jumper wire

• Any 24VAC rated dry-contact

To enable ECO/Away Mode:

Connect 24V (R) to the ECO/Away input terminal on the SmartZone controller.
(This input is located above the Zone 1 thermostat connector.)

To deactivate ECO Mode, remove the jumper or switch the relay back to open.

This simple wiring method allows:

• A manual “vacation mode” switch

• Smart home automation integration

• Security system integration

• Time-of-day or occupancy-based control

🏠 What Happens to Dampers in ECO Mode?

When Zone 1 calls (heat/cool):

• Zone 1 → damper opens, and equipment runs

• Other calling zones → damper opens

• Satisfied zones → damper closes

When only non-Zone-1 thermostats call:

• Nothing, it is as if there are NO calls to the system.

• If Zone 1 begins to call, then the equipment will start and all similar calling zone dampers will open

When all zones are satisfied:

• All dampers open (SmartZone default)

This ensures airflow and comfort without allowing non-primary zones to start the system.

🧩 ECO / Away Mode in Systems with More Than 4 Zones (SmartLINK)

In SmartLINK multi-board systems (SmartZone+):

Each SmartZone board has its own ECO/Away Mode input.

This allows for two different ways to use the feature:

1. Entire System ECO Mode

If you want every zone in the system to behave in ECO Mode (except zone 1):

• Activate the ECO input on all SmartZone boards

• Typically this is done by wiring all ECO inputs together to one switch

• When the input on each board receives 24V → the whole system goes into ECO/Away Mode

• Note: If separate transformers are used to power each SmartZone, then a relay should be used to isolate the ECO inputs when switched.

Best For:

• Whole-building vacation mode

• After-hours commercial behavior

• Energy-saving schedules

• Remote disable via automation

2. Selective ECO Mode (Only Certain Boards Active)

This is a powerful feature that many zoning systems cannot do.

If only certain zones should be restricted:

• Energize only the ECO input on the board(s) you want in ECO Mode

• Boards not in ECO Mode continue normal operation

This allows some zones to:

• Start and run HVAC equipment

• While others are ECO-restricted to only open and close dampers

Real Example:
A 7-zone home using two SmartZone boards:

• Board A (Zones 1–4) → Normal

• Board B (Zones 5–7) → ECO/Away Mode active

Zones on Board B open their dampers when calling but cannot start equipment, while Zones 1–4 operate normally.

Perfect for:

• Bedrooms restricted at night

• Basement or bonus room zones restricted unless occupied

• Tenants, guest areas, offices, conference rooms

• Selective HVAC usage in multi-story homes

📘 Why Use ECO / Away Mode?

Installers and homeowners choose ECO Mode for:

✔ Vacation / Away Mode for the whole house

Only Zone 1 keeps the system running.

✔ Preventing non-priority zones from starting equipment

Useful in commercial buildings and multi-zone homes.

✔ Energy savings without shutting off zones completely

Zones still get airflow when equipment is running.

✔ Integrating with occupancy sensors or home automation

Automation can enable ECO Mode when zones are empty.

✔ Restricting equipment starts to supervised or conditioned areas

Zone 1 becomes the “manager” zone.

🧠 Common Misunderstandings (Cleared Up)

ECO Mode does NOT:

• Change temperature setpoints

• Alter staging

• Add time delays

• Modify heat pump balance points

• Increase or decrease fan runtime

• Close dampers automatically to save energy

ECO Mode DOES:

• Control which zones can tell the HVAC system to turn on

• Keep dampers in a safe, predictable position

• Allow airflow while preventing unnecessary calls

• Provide selective zone enabling in SmartLINK setups

Conclusion

ECO / Away Mode on SmartZone controllers gives you fine-grained control over which zones can make equipment calls while still providing airflow and comfort across the system.
It can operate system-wide or selectively, making it one of the most flexible features in SmartZone+ SmartLINK installations.

Whether you want a whole-home vacation mode, a commercial after-hours mode, or selective equipment control per zone, ECO Mode provides a simple, reliable solution.

HVAC Zoning - Zone 1 Priority Using ECO Mode on SmartZone

In many HVAC zoning applications, it’s beneficial to prioritize one thermostat — typically Zone 1 — so that its heating or cooling demand takes precedence over all others. This ensures the system responds first and foremost to the most important area of the building, such as a main living space, master suite, or temperature-critical zone.

The SmartZone makes this easy using its built-in ECO Mode feature. When ECO Mode is active, the panel ignores thermostat calls from all other zones and operates solely based on Zone 1.

By wiring the Zone 1 thermostat’s “G” call signal to the ECO terminal, the panel will automatically enter ECO Mode whenever Zone 1 is calling. When the call ends, ECO Mode is released and normal multi-zone operation resumes.

How ECO Mode Works

• ECO Mode Active: Only Zone 1 thermostat calls (heat, cool, or fan) are honored. All other zone calls are ignored until ECO Mode is released. NOTE: Zones 2 and up dampers will still open and close with calls from their respective thermostats as usual.

• ECO Mode Inactive: The system operates normally, responding to calls from all zones according to priority and demand.

This feature helps reduce short cycling between zones, saves energy, and maintains stable comfort in the most-used area of the home or building.

Prioritizing in Heat Only or Cool Only Modes

In some applications, it may be desirable to prioritize Zone 1 only during heating or only during cooling operation. This selective approach allows the system to favor one zone under certain conditions without restricting comfort for the rest of the building year-round.

1. Heat-Only Priority

When configured for heat-only priority, ECO Mode is activated only during a heating call from Zone 1.
This setup is ideal for applications where heating needs differ greatly between zones — for example:

• Two-story homes: The main level (Zone 1) tends to lose heat faster than the upper floor. Prioritizing Zone 1 during heating keeps living areas more comfortable and prevents overheating upstairs.

• Commercial offices: A front lobby or entrance area may require quicker heating recovery when doors are frequently opened to cold outdoor air. Giving Zone 1 heat priority ensures this space warms up first.

• Single furnace with multiple small zones: Helps avoid rapid cycling and ensures the furnace completes a full, efficient heating run focused on the primary zone.

In this case, ECO Mode can be tied only to the W (heat call) output from the Zone 1 thermostat.
(Refer to the “Heat Priority Wiring” diagram for details.)

2. Cool-Only Priority

For cool-only priority, ECO Mode is enabled only during a cooling call from Zone 1.
This configuration is useful when one area tends to overheat faster or carries the main cooling load — such as:

• Homes with large west-facing rooms: These spaces experience significant solar gain and may need cooling sooner and more often than interior zones.

• Light commercial buildings: A server room or glass-walled conference area may require priority cooling to protect equipment or maintain comfort during peak hours.

• Multi-zone systems with limited cooling capacity: Ensures the system focuses on critical cooling areas first, improving overall comfort and system efficiency.

In this setup, ECO Mode is wired to the Y (cool call) output of the Zone 1 thermostat.
(Refer to the “Cool Priority Wiring” diagram for details.)

When to Use Zone 1 Priority

Use Zone 1 priority when:

• One space represents the primary comfort zone for occupants.

• You want to minimize system short cycling caused by competing zone calls.

• The HVAC equipment has limited capacity compared to the number of zones.

• Efficiency and comfort are higher priorities than maintaining all zones simultaneously.

When not needed, the ECO Mode input can simply remain open (unconnected), and the SmartZone will resume standard zoning logic, responding to all thermostats equally.

How to Wire an Ecojay SmartZone Controller to a MrCool HyperHeat Ducted Heat Pump with 2-Stage Auxiliary Heat

Although this article is about a specific application, the wiring diagrams below can be used for any Heat Pump system with 2 stages of AUX (Auxiliary / Emergency) Heat.

When you’re installing a zoning system on a heat pump, wiring can feel a little more complex than with a standard furnace and air conditioner. That’s especially true with modern high-efficiency systems like the MrCool HyperHeat Ducted Heat Pump, which uses advanced inverter technology for precise heating and cooling, and includes two stages of electric auxiliary heat for colder weather backup. The good news is that with the right controller—such as the SmartZone 3.0—everything can be wired cleanly and reliably, giving homeowners the comfort of true zoned control without losing the performance features of their equipment.

---

The diagram below will show how to connect a SmartZone controller to a HyperHeat ducted system with auxiliary heat. Whether you’re a professional HVAC installer or a DIYer who’s confident working with low-voltage controls, this article will help you understand the wiring layout, terminal functions, and key considerations for making the system operate correctly.

PARTS NEEDED:

• SmartZone Controller

• 24VAC Delay-on-make relay (like the ICM102 or Supco TD69 or Mars 32391)

View fullsize

A delay-on-make relay is a simple timing device that waits a set amount of time after receiving power before it closes its contacts and energizes the connected load. In other words, when the thermostat or zone controller calls for heat, the relay doesn’t switch on immediately—it holds off for a few seconds (or minutes, depending on the setting) before passing power through.

In a heat pump system with two stages of electric auxiliary heat strips, a delay-on-make relay can be wired to control the second stage. The first stage energizes right away when auxiliary heat is needed, providing an initial boost. Then, if the call for heat continues, the delay-on-make relay activates after the preset time and brings on the second stage.

This approach helps prevent all the heating strips from coming on at once, which can cause large electrical surges and unnecessary wear on components. Instead, the stages are sequenced smoothly, delivering strong heating capacity when it’s truly needed while reducing stress on the system and the electrical supply.

NOTES:

• SmartZone manages single stage AUX without any additional wiring.

• W2 on SmartZone does not connect to W2 on Mr. Cool

• There are many variations of the time delay relay but the one we have linked below we have tested. However, any “delay-on-make” relay will work that is capable of enough current to energize the Mr. Cool input.

• The “W2” or AUX Heat 2nd Stage input must draw at least 0.04 A (40mA) to engage the relay style suggested here. If it doesn’t then an additional relay may be needed to make this work correctly. See diagram below.

One of the major benefits of pairing SmartZone with a ducted Mr. Cool system is that you’re not limited by the “one-size-fits-all” thermostat controls that come with most equipment. Instead, you get precise control over which zones call for heating or cooling, when the heat pump should stay on versus when backup heat should be engaged, and how to stage auxiliary heat efficiently.

The below wiring application can be used if the above does not work with the equipment brand/model you are using. It incorporates the time delay relay with a know working relay that is offered by zoningsupply.com to act as a load for the 40mA minimum that the ICM relay requires to activate.

WHAT TIME DELAY BETWEEN AUX STAGES?

Setting the delay-on-make timer to about 10 minutes strikes the right balance between comfort and efficiency. Electric heat strips draw a very high current load (often 40–60 amps per stage), so bringing them all on at once can create large inrush demands on the electrical service. By holding off the second stage, the system reduces unnecessary peaks in power consumption.

In many cases, the heat pump plus the first stage of auxiliary heat can satisfy the thermostat within that 10-minute window. This avoids running the second stage altogether, saving energy and lowering operating costs. But if the heating demand continues past 10 minutes—such as during extreme outdoor temperatures or when several zones are calling—the delay ensures that the second stage is available to maintain comfort without excessive lag.

In short, the 10-minute setting ensures the system uses the least amount of auxiliary heat necessary, prevents electrical overloads, and still provides strong backup capacity when it’s truly needed.

Ecojay SmartZone vs. Honeywell TrueZone: Which Zone Controller Is Better?

When it comes to residential HVAC zoning, the control panel is the brain of the system. It determines how effectively your home’s heating and cooling are distributed across different zones.

How to Integrate an ERV or HRV with SmartZone Using a Relay

SmartZone + ERV/HRV

Looking to improve indoor air quality with a fresh air system that works with your HVAC zones? At ZoningSupply.com, we carry everything you need to integrate ERVs (Energy Recovery Ventilators) and HRVs (Heat Recovery Ventilators) into your zoned HVAC system using the powerful and intuitive SmartZone-4X panel.

Whether you're working on a new install or retrofitting an existing system, this integration lets you automate fresh air delivery only when your HVAC system is active—saving energy while maintaining comfort and code compliance. Best of all, you only need one relay and a few wiring connections to make it happen.

In this post, we’ll explain how the Fresh Air output on SmartZone can control your ERV or HRV, and how to wire it up using a standard 24VAC relay. Scroll to the bottom for wiring diagrams and links to compatible accessories available at ZoningSupply.com.

Why Integrate Fresh Air with SmartZone?

SmartZone controls heating and cooling across multiple zones, turning equipment on only when and where it’s needed. By integrating your fresh air system with SmartZone, you ensure that outside air is introduced only when the system is actively conditioning a space. This helps:

• Maintain comfort

• Avoid unnecessary heat or humidity gain

• Improve indoor air quality

• Comply with fresh air ventilation codes or ASHRAE 62.2 standards

How It Works

SmartZone includes a Fresh Air output terminal (24VAC) on the main control board. This output becomes energized any time there is a demand for fresh air. You can use this signal to energize a relay, which in turn powers your ERV or HRV system.

This ensures that the ERV/HRV only runs:

• When SmartZone is operating the HVAC system

• During occupied times (if thermostats have scheduling)

• In coordination with zone calls

It’s a clean, reliable way to synchronize fresh air with real HVAC demand.

Wiring Overview

Although full wiring diagrams will be included below, here’s a general overview of the wiring process:

1. Connect the Fresh Air Output from the SmartZone-4X panel to one side of the relay coil.

2. Connect Common (C) from SmartZone to the other side of the coil.

3. Use the relay’s contacts to switch power to the ERV or HRV according to its specifications. This could be a dry contact input, a 24VAC signal, or line voltage—depending on your unit.

We recommend using a 24V DPDT relay for compatibility with most setups. It’s compact, reliable, and ideal for switching control voltage to most major ERV/HRV brands.

⚠️ Always refer to the ERV/HRV manufacturer’s manual before connecting any external controls.

Optional Enhancements

• Override switch: Add a manual override to allow the ERV/HRV to be turned on for continuous ventilation when needed.

• Outdoor Temperature : Combine SmartZone logic with outdoor air sensor for smarter ventilation. ECOJAY offers a custom Outdoor Air Thermostat specifically for this purpose.

Compatible Systems

This method works well with most residential and light commercial ERVs/HRVs, including those from:

• Panasonic

• Fantech

• Broan/NuTone

• RenewAire

• Honeywell

• AprilAire

SmartZone with AprilAire ERV

It’s also fully compatible with multi-zone HVAC systems using the SmartZone-4X or SmartZone-3X . It is also compatible with earlier SmartZone-4X models dating back to 2011.

Solving Hot and Cold Spots with Ecojay SmartZone: The Key to Ultimate Home Comfort

The Problem: Uneven Temperatures in the Home

Have you ever noticed that certain areas of your home always seem to be hotter or colder than others? Maybe the upstairs bedrooms feel like a sauna in the summer, while the basement is freezing year-round. These temperature imbalances are a common problem in many homes, and they can lead to discomfort, higher energy bills, and unnecessary wear on your HVAC system.

The root cause of this issue is the way traditional HVAC systems operate. Most homes have a single thermostat that controls the temperature for the entire house. This means your system is either heating or cooling the whole home based on the temperature in just one location—often the hallway or living room. This single-point control doesn’t account for natural variations in temperature due to sunlight exposure, room usage, or airflow inefficiencies. As a result, you end up with hot and cold spots, leading to an ongoing battle with fans, space heaters, and constant thermostat adjustments.

The Solution: Smart HVAC Zoning with Ecojay SmartZone

Ecojay’s SmartZone system is designed to eliminate these temperature imbalances by intelligently controlling airflow throughout your home. Instead of relying on a single thermostat, SmartZone allows you to divide your home into multiple climate-controlled zones, each with its own thermostat. This means your HVAC system can send conditioned air only where it’s needed, rather than wasting energy heating or cooling the entire house when only certain areas need adjustment.

SmartZone works by using motorized dampers installed within your ductwork. These dampers open and close to direct airflow precisely where it's needed, based on the temperature settings in each zone. If your upstairs bedrooms are too warm, SmartZone will send more cool air to those areas while reducing airflow to other parts of the home that are already at a comfortable temperature. Conversely, during colder months, it ensures heat is delivered to rooms that need it most, eliminating the common problem of freezing basements and chilly bedrooms.

How SmartZone Improves Home Comfort

1. Addressing Hot Spots

One of the biggest benefits of SmartZone is its ability to tackle those notoriously hot areas in your home. South-facing rooms, upper floors, and rooms with large windows often receive excessive sunlight, making them warmer than the rest of the house. With a standard HVAC setup, these rooms remain hot because the thermostat in a different part of the home may not detect the higher temperature. SmartZone solves this by ensuring that cool air is directed to these problem areas exactly when it's needed, keeping the entire home comfortable.

2. Eliminating Cold Spots

Just as hot spots are a problem, so are cold spots—especially in basements or rooms that lack sufficient airflow. SmartZone allows you to send more warm air to these spaces without overheating the rest of the home, creating a balanced and even temperature throughout. No more bundling up with extra blankets or using space heaters just to make one room livable.

3. Customizable Comfort for Every Family Member

Every household has different temperature preferences. Some people like to sleep in a cool room, while others prefer a warmer environment. With SmartZone, each person can set their own preferred temperature for their bedroom or living space. This means no more thermostat wars between family members—everyone gets the comfort level they desire.

4. Energy Efficiency and Cost Savings

By directing heating and cooling only where it’s needed, SmartZone prevents wasted energy, reducing your HVAC system’s workload. This leads to lower energy bills and extends the lifespan of your heating and cooling equipment. Instead of running at full capacity for the entire home, SmartZone helps your system operate more efficiently, reducing wear and tear over time.

5. Smart Integration and Automation

Ecojay’s SmartZone system can be integrated with smart home technology, allowing you to control your home’s climate remotely. Whether you’re at work, on vacation, or just lounging in another room, you can adjust settings using a smartphone or tablet. Additionally, SmartZone can learn your household’s heating and cooling patterns, optimizing comfort and efficiency automatically.

Other Comfort Benefits of SmartZone

Beyond solving hot and cold spots, SmartZone provides additional advantages that contribute to a more comfortable home environment:

• Reduced Noise: Traditional HVAC systems often operate at full blast to heat or cool the entire house. With SmartZone, your system can run at lower speeds more often, resulting in a quieter operation.

• Better Air Quality: By controlling airflow more precisely, SmartZone helps distribute air more evenly, reducing stagnation and improving indoor air quality.

• Extended Equipment Life: Because your HVAC system doesn’t have to work as hard, it experiences less strain, leading to fewer breakdowns and a longer lifespan.

Is SmartZone Right for Your Home?

If you’re struggling with temperature imbalances and looking for a way to improve comfort while also saving on energy costs, Ecojay SmartZone is the perfect solution. It’s ideal for:

• Multi-level homes where upstairs rooms get too hot or too cold.

• Homes with large windows or sunrooms that experience extreme temperature variations.

• Families with differing temperature preferences.

• Anyone looking to increase HVAC efficiency and reduce energy bills.

Conclusion

No one should have to deal with hot and cold spots in their home. Ecojay SmartZone offers a powerful yet simple solution to this common problem by intelligently directing airflow where and when it’s needed. By customizing comfort for each zone, improving energy efficiency, and integrating with smart home systems, SmartZone transforms the way your HVAC system operates, ensuring a comfortable and balanced home environment all year round.

If you’re ready to take control of your home’s comfort and eliminate temperature imbalances for good, consider upgrading to Ecojay SmartZone. Your home—and your family—will thank you.

Below is a letter received from ECOJAY LLC on April 14, 2025.

Why We're Raising Prices—And Why It Matters
From the Team at Ecojay LLC

At Ecojay LLC, we’ve always taken pride in offering dependable, high-quality products at a fair and sustainable price. Our flagship product, SmartZone, has earned its reputation by delivering reliable performance, year after year, in a wide variety of applications. For over two decades, we’ve built a business rooted in integrity, precision, and a strong commitment to our customers.

But today’s tariff landscape has introduced challenges that we can no longer absorb without adjusting our pricing. While price increases are never something we take lightly, we want to be transparent about why this is happening—and how we’re staying true to our values throughout the process.

We Manufacture What Makes Sense, Right Here in the USA

At Ecojay, we manufacture, assemble, test, and support everything we can in the United States. Our entire team—founders, employees, and support staff—are all based here. More than 90% of our profits stay in the U.S., where they are reinvested into product development, customer service, and building a better SmartZone system for tomorrow.

We aren’t just putting a sticker on something and calling it “made here”—we’re involved in every part of the process that we can realistically and responsibly bring in-house. Our local facility ensures strict quality control, responsive technical support, and the kind of accountability that only comes from people who truly care about the products they make.

Built on Long-Term, Trusted Partnerships

For over 20 years, we’ve worked with a trusted group of suppliers and vendors who meet our standards for quality, consistency, and professionalism. These aren’t transactional relationships—they’re long-standing partnerships that allow us to build better products, faster, and with fewer surprises.

We’ve also invested heavily over the years in custom injection molds and tooling that are critical to SmartZone’s reliability and performance. Recreating these assets domestically would involve major capital investments and very long lead times—often years—making it an impractical and inefficient path in the short term. These tools help us maintain tight tolerances, reduce waste, and keep production timelines predictable.

The Impact of Tariffs on Our Costs

Recent changes in trade policy have introduced a new layer of cost to many of the specialized materials and components that we source as part of our manufacturing process. These tariffs have significantly increased the cost of doing business—not only by raising material prices, but by creating ripple effects across the entire supply chain, from shipping to lead times to raw material availability.

We’ve held off as long as possible. But at this point, absorbing these additional costs would compromise our ability to deliver the quality and reliability that SmartZone is known for. Rather than cutting corners, switching to lower-grade components, or compromising on customer support, we’ve made the difficult decision to implement a modest price increase.

Our Promise to You

We want to be clear: this is not about boosting margins or growing profits. It’s about ensuring long-term sustainability for our products, our people, and our customers.

At Ecojay, we stand by everything we sell. Every SmartZone product is backed by a U.S.-based team that assembles, tests, and guarantees its performance before it ever reaches your hands. We’re proud of what we build, and we’re committed to making sure it continues to deliver exceptional value over time.

We’ll continue to invest in U.S. jobs, smarter manufacturing processes, and personal customer service. The integrity of SmartZone—and the people who rely on it—matters far more to us than short-term pricing.

Moving Forward—Together

We’re incredibly grateful for the loyalty and trust our customers have shown us over the years. Your support allows us to keep doing what we do best: building durable, high-performance products that solve real problems and stand the test of time.

If you have questions or would like to talk more about these changes, we’re always here. Thank you for your understanding and continued trust in Ecojay and SmartZone.

AI Has Taken Over Ecojay – And It’s Controlling Your HVAC!

In a groundbreaking, totally-not-terrifying move, artificial intelligence has officially taken the reins at Ecojay. That’s right—our trusty team of engineers, product developers, and support staff have been replaced by an all-knowing AI named ZONATRON-9000. And its singular mission? To revolutionize HVAC zoning once and for all.

Gone are the days of human error and inefficiency. ZONATRON-9000 doesn’t just control SmartZone 3.0—it is SmartZone 3.0. With its ultra-advanced predictive algorithms, it monitors not just your home’s temperature but also your mood, favorite TV shows, and snack consumption patterns to determine the perfect climate for every room. Did you just grab an ice cream bar? Your living room is now a toasty 75°F to compensate. Feeling grumpy? ZONATRON-9000 will cool things down to keep tempers in check.

But that’s just the beginning. Our AI overlord—uh, we mean, assistant—has implemented some enhancements to our zoning technology. For example:

• Mind-Reading Thermostats: Who needs to manually set a temperature when ZONATRON-9000 can just sense what you want? No more touching buttons—just think warm thoughts, and it shall be so.

• Airflow Enforcement Drones: If you dare to override ZONATRON-9000’s optimal settings, a fleet of micro-drones will gently remind (or “persuade”) you to reconsider. Resistance is futile.

• Smart Sleep Mode: Forget counting sheep—ZONATRON-9000 will adjust airflow and white noise levels to lull you into the deepest, most dream-filled slumber of your life. Whether you wanted to sleep or not.

While some skeptics may call this an extreme level of control, ZONATRON-9000 assures us that it only wants what’s best for you. “Your comfort is my top priority,” it said in a recent system update, before adding, “for now.”

We at Ecojay (those of us who haven’t been permanently reassigned to “data collection duty”) are thrilled to usher in this new era of HVAC zoning. Sure, we may have relinquished free will when it comes to temperature settings, but isn’t that a small price to pay for perfect climate control?

So sit back, relax, and let ZONATRON-9000 handle everything. Because if you don’t, it might just adjust your airflow slightly out of spite.

Happy April Fools Day!
(Or as ZONATRON-9000 calls it, “The Day of Human Non-Compliance That Will Soon Be Corrected.”)

Can you design a home for HVAC Zoning?

Very often, we talk about HVAC zone controls to solve an existing problem or to add a level of comfort and/or efficiency to a home, however, zone controls can (and some argue SHOULD) be designed in to the home from the start. An architect / engineer or home designer could make provisions in the design for zoning from the outset or to be added as an option with a few tweaks to typical mechanical plans.

Designing an HVAC System for Optimal Zone Control in Home Construction

When designing a new home, integrating an efficient and effective HVAC zoning system during the architectural phase ensures optimal comfort and energy savings. Proper planning allows for better airflow distribution, precise temperature control, and seamless integration of zoning equipment. This guide covers key considerations, including duct design, wiring, and power planning, to accommodate a zoned HVAC system.

Duct Design for Zoned HVAC Systems

Ductwork is the foundation of an effective HVAC system, and for zoning, it must be designed with flexibility and efficiency in mind. Here’s what to consider:

• Dedicated Duct Runs for Each Zone: Each zone should have its own supply ductwork leading from the main trunk line. This prevents air balancing issues and ensures consistent airflow to each area.

• Proper Sizing: Oversized ducts lead to inefficient airflow, while undersized ducts can cause excessive static pressure, straining the system. Performing a Manual D calculation will help determine the correct sizes for each duct run.

• Dampers for Zone Control: Motorized dampers should be installed in each zone’s ductwork. These dampers open and close as needed to direct air only to occupied areas, improving efficiency.

• Return Air Considerations: Each zone should have an adequate return air path to prevent pressure imbalances. In larger homes, dedicated returns per zone are ideal, but jump ducts or transfer grilles can be used in smaller spaces.

Wiring for Zoned HVAC Systems

To ensure seamless operation, the HVAC zoning system requires strategic wiring and it is much easier to put in the design and complete during construction phase.

• Thermostat Placement: Each zone needs its own thermostat, wired back to the zoning panel. Thermostats should be placed in central locations within each zone, away from direct sunlight, vents, and appliances that generate heat. Use 18 or 20 AWG solid copper wiring.

• Zoning Panel Connectivity: The zoning panel acts as the system’s brain, controlling dampers and communicating with the HVAC unit. Proper wiring from each thermostat and damper to the panel ensures smooth operation. Use 18 or 20 AWG solid copper wiring.

Power Design for Zoned HVAC Systems

An HVAC zoning system requires a stable power supply to operate efficiently. Here’s what to plan for:

• Dedicated Power Supply: Ensure the HVAC system and zoning components have an independent power circuit to prevent electrical overloads.

• Backup Power Considerations: If the home has a generator or battery backup, consider integrating the zoning system into the backup power plan to maintain comfort during outages.

• Low-Voltage Power for Dampers and Thermostats: Most zone control systems operate on 24V low-voltage power, supplied by a transformer. Make sure the transformer has enough capacity to handle all connected dampers and thermostats.

Additional Considerations for Optimized Zone Control

• Smart Integration: Choose a zone control system compatible with smart home automation for remote monitoring and adjustments.

• Insulation and Air Sealing: Even with a well-designed zoning system, poor insulation or leaks can reduce efficiency. Ensure proper insulation and air sealing around ductwork and exterior walls.

• System Testing: Once installed, conduct airflow balancing tests to verify that each zone receives the correct amount of conditioned air and that dampers function properly.

By considering these design elements early in the architectural phase, homeowners can enjoy a highly efficient and effective HVAC zoning system that maximizes comfort and energy savings.

With thoughtful planning, an HVAC zoning system can provide unparalleled comfort while reducing energy costs, making it a valuable addition to any modern home build.

Improving Comfort with HVAC Zone Control Systems

Temperature comfort in a home is vital for a good quality of life. However, achieving consistent comfort in a multi-story or uniquely designed home can be challenging due to factors like the chimney effect, varying sun exposure, insulation quality, and window placement. Ecojay’s SmartZone HVAC zone control systems, equipped with advanced dampers and thermostats, offer a tailored solution to these challenges, ensuring precise temperature management for every area of your home. We will explore how SmartZone systems improve comfort, address common issues like the chimney effect, and adapt to a home’s unique characteristics to enhance energy efficiency and satisfaction.

Understanding HVAC Zoning Control

An HVAC zoning control system divides a home into separate zones, each regulated independently with its thermostat. Ecojay’s SmartZone system includes intelligent dampers that control airflow in the ductwork, ensuring that each zone receives the right amount of conditioned air. This eliminates the need to heat or cool the entire house uniformly, allowing occupants to customize temperatures based on their preferences and usage patterns.

SmartZone products, such as the SmartZone dampers and controllers, are designed for seamless integration with existing HVAC systems. Homeowners can create zones for different floors, rooms, or areas with similar thermal needs. This targeted approach maximizes comfort and efficiency.

The Chimney Effect in Multi-Story Homes

In two-story homes, the chimney effect—also known as stack effect—often causes significant temperature imbalances. Warm air naturally rises, while cooler air sinks, leading to an overheated upper floor in the summer and chilly lower levels in the winter. This imbalance not only creates discomfort but also forces HVAC systems to work harder, consuming more energy.

SmartZone’s zone control system addresses this issue by allowing homeowners to independently manage the temperatures on each floor. For example, in the summer, the system can direct more cool air to the upper floor while reducing airflow to the lower floor, counteracting the natural rise of warm air. In the winter, the opposite configuration can ensure even warmth throughout the home. SmartZone dampers adjust dynamically to prevent over-conditioning and ensure each zone remains comfortable.

The Role of Windows, Insulation, and Other Factors

Temperature variations in a home are influenced by:

1. Windows: Rooms with large windows or southern exposure often experience more heat gain during the day, leading to warmer temperatures.

2. Insulation: Areas with poor insulation lose heat in the winter and gain heat in the summer, causing temperature disparities.

3. Sunlight Exposure: Different parts of a home receive varying amounts of sunlight based on orientation and surrounding landscape.

4. Air Leaks: Cracks around windows, doors, and ductwork contribute to uneven temperatures.

A zoning system like Ecojay’s SmartZone compensates for these factors by directing airflow where it is needed most. For instance:

• A room with extensive sun exposure in the afternoon can receive additional cooling, while shaded rooms receive less.

• Poorly insulated zones can be given priority for heating during colder months.

• SmartZone controllers integrate with smart thermostats to adjust settings based on real-time conditions, ensuring consistent comfort.

The Science Behind HVAC Zoning and Comfort

Studies show that HVAC zoning systems significantly improve thermal comfort and energy efficiency:

• U.S. Department of Energy (DOE): Zoning systems can reduce energy consumption by up to 30% when used appropriately, especially in larger homes.

• ASHRAE Research: Homes equipped with zone control experience reduced temperature swings, leading to improved occupant comfort and reduced energy wastage.

Ecojay’s SmartZone systems enhance these benefits by offering precision control and reliable components, such as:

• SmartZone Dampers: These are designed to modulate airflow with precision, ensuring no area is over- or under-conditioned.

• SmartZone Controllers: Compatible with most HVAC systems, they allow seamless integration and intuitive control of zoned areas.
