Do HVAC Zone Control Systems save Energy?

An HVAC zone control system with dampers and thermostats in each area of your home can save energy, provided it is designed, installed, and operated correctly. The principle behind this system is simple: instead of conditioning the entire house to the same temperature, it allows targeted control of heating and cooling in different zones based on occupancy and preferences. However, like any energy-saving solution, its effectiveness depends on specific circumstances, and there are skeptics who argue otherwise. This article will examine the energy-saving potential of zoned HVAC systems, address common counterarguments, and support its efficiency with evidence and expert insights.

How Zoned HVAC Systems Work

A zoned HVAC system divides a home into different areas, or zones, each equipped with its thermostat. Dampers installed within the ductwork regulate airflow to these zones, opening or closing based on the desired temperature set on the thermostat. For instance, you might prefer your bedroom cooler at night while keeping the living room unconditioned. A zone control system achieves this without wasting energy conditioning unused spaces.

1. Reduced Energy Consumption in Unused Areas

One of the main arguments in favor of zoned HVAC systems is their ability to focus heating and cooling efforts where they are needed. Homes often have spaces that are infrequently used, such as guest rooms, basements, or storage areas. Conditioning these areas to the same level as occupied spaces leads to unnecessary energy use. By selectively reducing or eliminating airflow to these areas, zoned systems can cut down energy consumption significantly.

2. Adaptability to Occupancy Patterns

Zoned systems allow for dynamic adjustments based on when and where people spend their time. For example, during the day, you might only need to cool your home office, while the bedrooms remain unused. At night, the system can prioritize the bedrooms and reduce energy use in other zones. This adaptability ensures efficient energy use tailored to your lifestyle.

3. Improved HVAC Efficiency

Heating and cooling systems often work harder to maintain consistent temperatures across the entire home, especially in houses with varying sun exposure or insulation levels. Zoned systems mitigate this by allowing specific temperature settings for different zones, reducing the workload on the HVAC unit. This can extend the lifespan of the equipment and lower energy costs.

4. Enhanced Comfort Leading to Energy Savings

A home that feels more comfortable is less likely to prompt extreme thermostat adjustments. Instead of setting the thermostat lower (or higher) than necessary to cool (or heat) an entire house quickly, occupants can maintain comfortable settings in specific zones. Consistency in settings reduces energy spikes associated with overworking the HVAC system.

Evidence Supporting Energy Savings

Research supports the energy-saving potential of zoned HVAC systems:

• U.S. Department of Energy (DOE): The DOE highlights that zoned heating and cooling can result in energy savings of up to 30% in some cases, depending on home size and usage patterns.

• Pacific Northwest National Laboratory (PNNL): A study on residential energy efficiency found that zoned systems reduced overall HVAC energy use by addressing overconditioning in unoccupied spaces.

• Independent Field Studies: Real-world implementations in homes equipped with smart thermostats and dampers demonstrate significant reductions in monthly energy bills, especially in large or multi-story homes.

Common Counterarguments and Rebuttals

Despite these benefits, some argue that zoned HVAC systems may not deliver meaningful energy savings. Let’s examine these points and provide counterarguments.

Argument 1: Increased Complexity and Maintenance Costs

The Argument: Critics suggest that the addition of dampers and multiple thermostats increases the system's complexity, leading to higher maintenance costs and potential malfunctions that negate savings.

The Rebuttal: While it’s true that zoned systems are slightly more complex, advancements in technology have made these systems more reliable and user-friendly. The long-term energy savings often outweigh the initial costs. When a SmartZone controller is installed with smart thermostats the zone control system operates behind the scenes with no need for maintenance or interaction after installation.

Argument 2: Limited Savings in Smaller Homes

The Argument: Skeptics argue that in smaller homes, the benefits of zoning are negligible since the HVAC system would already operate efficiently without zoning.

The Rebuttal: While savings might be less dramatic in smaller homes, they are still achievable if there are unoccupied areas. Furthermore, zoning improves comfort and system longevity, which adds indirect value even in smaller settings.

Argument 3: Inefficiency Due to Improper Installation

The Argument: Poorly installed systems may lead to air leaks or imbalanced zones, causing the system to work harder and use more energy.

The Rebuttal: While this is a valid point, proper installation will ensuring the system’s efficiency. With todays technology (SmartZone) the installation is easier than ever to get right and a homeowners could either select experienced contractor or install DIY and still get optimal performance.

Argument 4: Increased Equipment Use

The Argument: Opponents claim that cycling dampers and thermostats frequently might wear out the equipment faster, leading to higher replacement costs.

The Rebuttal: Modern zoned systems are designed to handle such operations and have for over 20 years with SmartZone. When properly installed and maintained, the equipment often operates more efficiently and lasts longer due to reduced overall load.

Best Practices for Maximizing Energy Savings

To ensure an HVAC zone control system delivers its energy-saving potential, consider the following practices:

1. Professional Design and Installation: Work with experienced HVAC professionals to design a zoning system tailored to your home’s layout and insulation properties.

2. Smart Thermostats: Pair the system with smart thermostats that learn occupancy patterns and optimize temperature settings automatically.

3. Regular Maintenance: Schedule routine inspections to ensure dampers, thermostats, and the HVAC system operate correctly.

4. Seal and Insulate: Address any ductwork leaks and improve home insulation to maximize efficiency.

5. Set Realistic Expectations: Avoid extreme temperature differentials between zones to prevent excessive strain on the HVAC system.

Bypass dampers are STUPID... or maybe not?

Should a zoning system have a bypass damper or not?

Zone control systems have become a vital aspect of modern HVAC systems, especially in multi-room homes or commercial spaces where temperature preferences can vary significantly between areas. By allowing different parts of a building to be heated or cooled independently, zone control systems offer energy efficiency, increased comfort, and better overall control. However, one aspect of zone control systems—bypass dampers—has been a point of debate within the HVAC industry. Some argue that bypass dampers are unnecessary or even counterproductive, while others highlight their benefits in specific scenarios. This article explores the case for using bypass in zone control systems, delving into the advantages, discussing counterarguments, and examining studies that underline its effectiveness.

What is a Bypass Damper?

A bypass damper is a component within a zone control system that regulates excess air pressure. In a zoned system, individual zones can close when their set temperatures are reached, creating excess air pressure in the ductwork as the HVAC system continues to operate for the remaining open zones. A bypass damper redirects this excess air back into the system’s return duct or to a common area, balancing the airflow, and relieving pressure within the ducts. This feature is particularly relevant in systems with variable or multiple zones, where sudden or partial closures can create imbalances.

Benefits of Using Bypass in a Zone Control System

1. Pressure Relief and Ductwork Protection

   One of the primary advantages of using a bypass damper in zone control systems is pressure relief. When individual zones close, pressure can build up in the system. If left unmanaged, this excess pressure can strain ductwork, potentially leading to leaks or damage over time. A study by the Building Science Corporation noted that excessive air pressure in HVAC systems can lead to duct leakage, which in turn reduces the system’s efficiency and increases the chances of indoor air quality issues like pollutant infiltration (Rudd, 2017).

   Bypass dampers address this issue by redirecting the excess airflow, maintaining a balanced pressure across the system. This can extend the lifespan of the ductwork and help prevent common issues related to over-pressurization, such as loud or “whistling” noises, which can be disruptive to homeowners.

2. Improved System Efficiency

   Efficient airflow management is crucial for maintaining an HVAC system's performance. According to a study published in ASHRAE Journal, bypass dampers help to reduce the system's energy use by maintaining the HVAC system’s optimal airflow rate, which prevents overworking the blower (Griffiths & Simmons, 2019). By keeping the blower from operating against high resistance, a bypass damper can reduce wear on the blower motor and help maintain efficiency over time.

   In addition, bypass dampers can help ensure consistent airflow across the evaporator coil in cooling systems. If airflow drops too low due to zone closures, the coil can get too cold, increasing the risk of freezing and reducing the system's efficiency. By allowing excess airflow to bypass closed zones, the damper helps maintain steady airflow, optimizing the cooling performance.

3. Enhanced Comfort and Flexibility

   Zoning systems are installed with the primary goal of providing individual comfort to multiple areas. When bypass is integrated, the system can function more flexibly, balancing between zones and maintaining airflow to areas that might otherwise experience drafts or pressure differentials. For example, in situations where two out of three zones close, a bypass damper ensures that excess airflow does not flood into the single open zone, preventing discomfort from excessive air supply.

   This capability is especially beneficial in homes with varying occupancy, where different rooms might frequently be turned on and off. By integrating bypass, contractors can offer homeowners smoother transitions and fewer temperature fluctuations, even as zones close and open at different times of the day.

Addressing Common Arguments Against Bypass Use

Despite these advantages, bypass dampers have their critics within the HVAC industry. Here are some of the main counterarguments, and how proponents of bypass dampers respond.

1. "Bypass Dampers Waste Energy"

   A common argument against bypass dampers is that redirecting air back into the return duct wastes conditioned air, making the HVAC system less efficient. Critics argue that the energy used to heat or cool the bypassed air is lost as it re-enters the system.

   While it’s true that bypass dampers cycle some conditioned air, studies show that the amount of energy “wasted” is relatively small and often outweighed by the system's overall efficiency improvements. For example, research by the Energy Efficiency Collaborative found that systems with bypass dampers maintained consistent blower operation and achieved slightly higher efficiency overall, due to reduced blower strain and optimal airflow (Johnson et al., 2020). Furthermore, bypass dampers are typically adjustable, allowing HVAC contractors to set the damper to open only when necessary, thus minimizing any potential loss of conditioned air.

2. "Bypass Dampers Can Cause Humidity Issues"

   Some HVAC professionals argue that bypassing air back into the return duct can increase humidity levels, particularly in cooling mode, by recirculating moist air. This effect can be especially pronounced in high-humidity environments, where any recirculated air could carry excess moisture.

   However, this issue is usually manageable. Properly designed systems with adjustable bypass dampers, paired with regular HVAC maintenance, can minimize the impact on humidity. By integrating a humidistat or smart HVAC controls, contractors can mitigate any potential increase in indoor humidity levels. Additionally, in well-designed systems, bypass usage is often infrequent enough that humidity concerns are minimal.

3. "Variable-Speed Blowers Make Bypass Obsolete"

   Another argument suggests that bypass dampers are unnecessary for modern HVAC systems equipped with variable-speed blowers. These blowers can adjust to varying airflow needs as zones open and close, reducing the need for bypass.

   While variable-speed systems offer flexibility, they don’t always eliminate the need for bypass. For instance, in multi-zone systems with high zoning variation, even variable-speed blowers may struggle to maintain optimal airflow without bypass assistance. Furthermore, bypass dampers can help in retrofit applications where variable-speed technology may not be feasible or cost-effective for the homeowner. In such cases, bypass dampers serve as a practical and economical solution for maintaining comfort and performance in zone control systems.

Recommendations for Contractors

For HVAC contractors, the decision to install a bypass damper should take into account the specifics of the system design and the client’s needs. Here are some guidelines to consider:

• Evaluate System Size and Zone Variation: In systems with a large number of zones or zones of significantly varying sizes, a bypass damper can help maintain balance and prevent pressure issues. For smaller systems or those with variable-speed blowers, bypass may be less critical but still worth considering in certain cases.

• Adjust Bypass Settings: Setting up the bypass damper correctly is essential. Adjust the damper to open only when necessary, preventing excessive recirculation of conditioned air while maintaining system balance.

• Consider Customer Comfort Preferences: Homeowners often prioritize comfort, and bypass dampers can make zoning systems more comfortable by reducing noise and drafts. When pitching the benefits of bypass to clients, highlight the potential for improved comfort and airflow balance.

• Plan for Maintenance and Education: Educate clients on the maintenance needs of their zone control system, particularly when bypass is involved. Regular HVAC check-ups will help maintain balance and efficiency, even as seasons change and different zones are utilized.

Conclusion

For many HVAC applications, bypass dampers serve as a valuable component within zone control systems, providing pressure relief, protecting ductwork, and enhancing both comfort and energy efficiency. While modern HVAC systems with variable-speed blowers can manage airflow more effectively than their single-speed counterparts, bypass dampers offer an additional layer of balance that can be particularly useful in multi-zone configurations or retrofit applications.

By considering the system’s specifics and the customer’s comfort preferences, contractors can make an informed choice on when bypass dampers are appropriate. Ultimately, when used strategically, bypass dampers can enhance the performance, longevity, and user satisfaction of zoned HVAC systems, making them a worthwhile consideration for many installations.

Honeywell Damper - Motor upgrade video instructions

If you have a broken Honeywell damper, don’t use these or you will end up replacing them again soon:

The Honeywell M847 or ARD or EARD or Hansen or Syncron motors are notorious for repeated failures when used in HVAD damper applications. This is usually due to a broken gear tooth or burned out motor. These are often referred to as “spring” motors because they rely on a spring to open. When 24VAC is applied to the motor, it draws over 6Watts when generated excessive heat especially in an attic that is already 120 degrees in the summer.

The issue with replacing these motors with something more reliable has traditionally been the shaft that is on the Honeywell damper is designed to ONLY fit this style of motor so it is easiest to just replace the motor with a new version of this low-quality motor. In the past, the only alternative to this was to replace the entire damper. Most of the time, the “blade” and “can” of the damper are still in great working condition even though the motor has failed so it is difficult to justify the time and cost of a full damper replacement in order to upgrade to a more reliable motor.

SO, Ecojay has released a product that allows the much more reliable Belimo motor to be used as a replacement. This “Shaft Adapter” allows for a simple and easy upgrade that will last many years longer than any alternative (and, at a lower cost).

The video below shows, in detail how to make this upgrade.

Connect SmartZone to any old 24V damper: Wiring instructions & more

For most modern HVAC dampers in the marketplace, the wiring terminals are labeled in an intuitive way. In other words, the terminals have labels like “OPEN” , “CLOSE”, or “24V” . This kind of labeling was not always the norm, and just a few years ago, most damper motors were either 2-wire and had NO labels or they were “5 wire” and the terminal labels were “1, 2, 3, 4, 5” thus, requiring a manual to decipher.

We have gotten calls from customers about dozens of different damper terminal labeling schemes. While there is some consistency. This is NOT always the case.

Over the years, we have released many different wiring diagrams for many different dampers and here we are attempting to create a list of all the damper wiring information we have compiled over the years.

2-Wire / Spring Dampers

One style of damper that is not shown here are 2-wire zone dampers (spring dampers) that have motors that look something like below. They all have one thing in common that you could probably guess… two wires. These wires are often not labeled and it is because the polarity does not matter. It only matters that one of them goes to the “COM” damper terminal on SmartZone and the other goes to either “OPEN” or “CLOSE”. This will depend on whether they are “Power-Open” or “Power-Close”. These types of hvac zone damper motors are powered in only one direction and they “spring” back into the opposite position. So, if you have “Power-Open” dampers the other wire should be connected to the “OPEN” terminal of the zone panel and if “Power-Close” then connect to the “CLOSE” terminal of SmartZone.

We always recommend considering an upgrade to our Power-Open / Power-Close (3-wire) damper. This style of damper uses 1/10 the power of “spring” dampers and is MUCH more reliable. Spring dampers have a typically shorter lifespan than the Belimo 3 wire dampers we are selling. We have tested MANY damper motors over the years because we stand behind everything we sell it is important for us to carry and ONLY sell high quality products. This is why we DO not sell a direct replacement for this two wire motor but instead offer a way to upgrade to a MUCH better technology that will outlast the 2 wire replacement many times over. All at a cost that is almost the same. Take a look at the M847 shaft adapter and see if it or any of the others we have will allow you to upgrade.

Is Zone Control really for everyone?

Why Your Residential and Light Commercial Forced-Air Systems Need a Zone Control System

In today's world, energy efficiency and personalized comfort are top priorities for homeowners and business owners alike. One technology that can significantly improve both is a zone control system for your forced-air heating and cooling systems. At ZoningSupply.com, we believe that implementing a zone control system, such as the SmartZone from Ecojay, can transform how you experience comfort in your home or business. Here’s why.

Understanding Zone Control Systems

A zone control system divides your home or business into different zones, each of which can be heated or cooled independently. This is achieved through the use of dampers installed in the ductwork and controlled by a central system that responds to separate thermostats placed in each zone. This allows for precise temperature control in different areas, leading to numerous benefits.

Benefits of Zone Control Systems

1. Enhanced Comfort

With a zone control system, you can maintain different temperatures in different areas of your home or business. For example, you might prefer a cooler bedroom at night but a warmer living room during the day. Zoning allows you to set the perfect temperature for each zone, ensuring optimal comfort for everyone.

2. Energy Efficiency and Cost Savings

Heating or cooling your entire home or business uniformly can lead to wasted energy and higher utility bills. Zone control systems reduce energy consumption by only conditioning the areas that need it, rather than the entire building. This targeted approach can lead to significant cost savings over time.

3. Extended HVAC System Lifespan

By reducing the workload on your HVAC system, zone control can help extend its lifespan. Since the system isn’t working as hard to maintain a uniform temperature throughout the entire building, there’s less wear and tear on the equipment. This can result in fewer repairs and a longer life for your system.

4. Improved Indoor Air Quality

Zone control systems can improve indoor air quality by ensuring that the HVAC system is not overworking and potentially spreading dust, allergens, and other pollutants throughout the entire building. By focusing on specific zones, it’s easier to manage and maintain cleaner air.

5. Customization and Control

Modern zone control systems, like Ecojay's SmartZone, offer advanced customization and control options. You can easily set schedules, make adjustments remotely, and monitor system performance, all of which contribute to a more efficient and user-friendly experience.

NEW Product: Common Wire Adapter Kit

Sometimes, when upgrading to SmartZone or even when upgrading to a new modern thermostat without zoning, the existing wires running to the old thermostat do not have enough conductors to make it operate properly. It can sometimes be an impossible task to run a new wire to the location where the thermostat or SmartZone panel is located. For some time, we have been recommending the use of an “Add-A-Wire” kit from LUX to solve this problem but we are now offering a solution from Vine called a COMMON WIRE ADAPTER. This new solution is available at ZoningSupply.com and can be added to any thermostat that needs an additional wire.

Existing: Three (3) wires, Needed for upgrade: Four (4) wires

Existing: Four (4) wires, Needed for upgrade: Five (5) wires

NEW Product: WiFi Thermostat Coming SOON

EDIT: Arrived in stock and shipping now!

PRE ORDER NOW (PRE-Release price)

For many years, we have been testing, evaluating, recommending thermostats for our customers. Some have been good and others awful but we have never found one that we were willing to endorse outright… until now. We are preparing to launch an amazing and low-cost WiFi thermostat on ZoningSupply.com

First, a little background. I have been testing thermostats for more than 20 years. I have some of the very first WiFi thermostats back before Ecobee ever existed. Then in 2008 ecobee released their first version of an internet connected thermostat (I bought 2 the day they were released). The US market became largely aware of “internet connected” thermostats at this point. These were pretty “crude” but we didn’t know that yet because they were all that was available. Next the NEST hit the market, 3 years later and for a while it was the gold standard. Even though other thermostat companies tried to jump on the bandwagon (Honeywell) there products were no match for the elegance and ease of the NEST. Ecobee released some better versions and these held their own with the NEST but at $250 average cost, these were still not for the masses. And the price point made them difficult to justify on a zoning system such as SmartZone because you needed to buy multiples (one for each zone). This has led us to look for a lower cost option so when you need to buy 3 or 4 to complete your zone control system, it doesn’t break the bank.

With this in mind, we have recommended a couple of different thermostats in the past. Predominantly, we have recommended the Wyze thermostat and the Ecobee3 Lite but both of these two have their cons. Although these are not bad choices, there were still not up to the standards we were looking for.

Over the last two years, many “low-cost” WiFi thermostats have hit the market. I have tested all of them and for the most part they all fall short of our standards in one way or another. An example of this is the “Amazon Thermostat” which is a decent thermostat for a lot of situations but it requires the installation of the APP just to configure it. Or the Sensi Lite thermostat which uses an aggressive power-stealing circuit across the W output and can make the equipment energized in Heat when not calling.

If anyone is interested in a comprehensive article about all my tests, please let me know in the comments. I plan to also make a video about this process and will put a link here when it is available.

This is an abridged list of the criteria we used for WiFi Thermostat evaluation. Almost none of the thermostats we tested met ALL of the below. We expect the basic functions of a thermostat to work simply and easily, beyond that, we also wanted something that would be a perfect match for our SmartZone system.

PRICE: Under $100

FUNCTION: Multi-Stage, Heat Pump, Gas, Electric, Dual Fuel, Fan: auto, on or circulation. Must be easy to navigate the menus, change modes and set temperature at the thermostat.

DETAILS: Scheduling & Configuration can be done on the thermostat, No need to use the APP at installation, 7 day programming

ENGINEERING: RELAYs (NOT triacs/solid-state) for equipment interface, Ability to install without a common wire but WITHOUT “power stealing”

BONUSES: Color touch-screen, high-quality knob for easy and quick adjusting temp

NEW Product: Stand Alone Damper Control using ANY Thermostat

Sometimes, full blown zone controls are not needed to solve an airflow or temperature related issue in the ducting of a home or other building.

One example might be a bonus room, a basement or a 3 season room that could benefit from some air occasionally but doesn’t necessitate a zone control system with all of the features included with our SmartZone products.

For these applications, we have developed a control board that can connect a thermostat directly to a damper for basic control.

With this Damper Direct Controller, you can simply connect any thermostat, a 24vac transformer & hook up your damper (ANY damper will work as long as it is 24V).

The applications for this product are too may to list but, for us, it is just one additional tool in the toolbox for managing comfort and efficiency of your home or building’s HVAC. Contact ecojay.com or us here at ZoningSupply if you have any questions or ideas.

Need MORE than 50VA for a large system? Use two transformers!

Not everyone knows that an AC transformers can be connected in parallel on the outputs to increase the total power output. A single 50VA transformer (like the one ZoningSupply.com offers) is capable of about 2 amps of output at 24VAC. This is more than enough for most typical systems up to 4 zones that have only 1 or two dampers per zone, however, some situations call for more dampers. If this is the case for your application, you can find some 75VA or even 100VA transformers for sale, but there is another way. If you use two transformers and connect them as shown in the image below, you will have a 100 VA output.

24V AC Transformer (50VA)

$24.99

One critical detail to note, these MUST be connect with the same “POLARITY” In other words, the two terminals on the left of the transformers must connect together and the two on the right must connect together.

It would be a good practice to plug both of these transformers into the same power strip to also ensure that the polarity is maintained on the 120Vac input as well.

New and improved power open/close damper motors available NOW!

We are exited to share our newest upgrade to the SmartZone system. We have worked with Belimo to provide the best damper motor in the industry for over 10 years and NOW it’s going to be even better!

Our standard Power Open / Power Close damper motor is now DOUBLE the mechanical power (torque) but still uses the same amount of electrical power. Is it a miracle? Is it magic? Have we finally perfected perpetual motion to conserve energy? Well… NO, it is a pretty basic matter of physics (rigid body mechanics). The motor is moving at a slower speed (60 seconds to travel 90 degrees instead of 35 seconds). This allows the gearing ratio to have a higher torque at the output shaft!

The slower speed motor may, at first, sound like a negative but in the world of dampers and HVAC ductwork there are many advantages. A slower speed means quieter movement & less air noise. It means higher reliability because of less wear on bearings & other moving parts. A slower motor can also improve the effectiveness of all types of pressure relief (Bypass, Dump Zones & SmartStatic).

In case you were wondering, the older 35 second motor will continue to work and be available for the next approximately 12 months. However, there is no issue with connecting some 35 second and some 60 second motors to a SmartZone system. They will play together nicely! You could even have a mix of motors on the same zone using the damper wiring splitter. This will allow anyone with an existing system to add a 60 second motor with no problems.

We are proud of this new motor improvement and want our customers to share in the excitement.

Prevent Axillary Heat from turning on manually!

There are sometimes certain circumstances that might necessitate an ability to manually turn OFF the axillary heat function of a Heat Pump.

When using a heat pump, it is usually necessary to have an “Axillary Heat” source for the times of the year when the weather is just too cold for the compressor to be effective enough to provide sufficient heat. Depending on the location or part of the world you live in, this could be electric heat strips, gas furnace (including propane), oil or even wood fired axillary heat. Depending on the cost of these resources, it is often desirable to prevent the AUX heat from running unless absolutory necessary. With SmartZone, the “AUX” heat is controlled automatically based on the supply air temperature (sensor included with SmartZone). For this reason, in order to prevent AUX heat from turning on when it is not wanted by the homeowner or user of the system we have two different methods possible.

The first method is to control AUX heat from ZONE 1 thermostat then set the thermostat to disable AUX heat under whatever conditions are desired. This method has two drawbacks, it does not prevent AUX heat when other zones are calling and it REQUIRES zone 1 to ever allow AUX heat to energize.

The second method is to use a relay and a manual switch to enable and disable AUX heat whenever desired. Below is a wiring diagram for how this method works. It is a full proof way to keep AUX heat from energizing when it is not needed/wanted. A link is below for the relay needed to make this work (Any standard wall switch from a ‘big box’ store will work)

NEW Product: Damper wiring splitter/breakout board

One question that we get quite often is: “Can I connect more than 1 damper to each zone of the SmartZone?” The answer is YES, up to 10 actually.

The next question is usually: “How do I do that since there is only a single terminal and only 1 wire will fit in each position?” The answer to this question is to use a short wire coming out of the terminal then wire-nuts or Wago connectors to attach how many wires needed to accommodate all the dampers you want.

This works fine and will continue to be an acceptable option but we decided that a more elegant solution was in order. SO, we designed the SmartZone Damper Wiring Splitter.

This wiring device allows 4 dampers (or more with daisy-chain) to easily be connected to any model SmartZone or other zone controller. It comes with screwless wiring terminals and LEDs to indicate open and close position of all dampers. It can be mounted using screws or double stick tape. The obsessive wiring nerd will love the clean and easy wiring that this device can accommodate.

If you have more than 4 (up to 10 dampers) per zone you can use the daisy-chain method to connect with the SmartZone Damper Wiring Splitter.

If you have this many (OR even more) dampers on your system, you should also check out this article about using a relay when necessary.

Sneak Preview... NEW SmartZone Enclosure is comming soon!

For over 10 years, ECOJAY has used it’s iconic enclosure for SmartZone and related products. It was first conceived as a drastic improvement and upgrade from the original SmartZone enclosure first brought to market almost 20 years ago.

The NEW enclosure (Verson 3) started in the design process during 2020 but was shelved because of obvious reasons. It was, thankfully, resurrected after an increased focus on weight reduction for shipping. This has given us the opportunity to tweak and improve some of the few shortcomings of the Version 2 enclosure.

With the aid of modern design tools such as Fusion 360 and 3-D printing for rapid prototyping, our process of designing a new enclosure is much more thorough and exacting. This means we could try lots and lots and lots of new things to dial in the most durable and user friendly enclosure system on the market.

COMING IN 2023

Over 30 Prototypes and as many tests for functionality and durability

FINALLY!!!! Fresh Air Control with Outdoor Temperature Control

In 2013, v8E firmware was released for SmartZone and since then we have had a vision of the perfect Outdoor Temperature Sensor/Controller to match with the built-in Advanced FRESH AIR capabilities of the SmartZone-4X.

More information about these FRESH AIR Features click here.

Until now, we have recommended several different methods to limit the function of Fresh Air when the outside air temperature is too high or two low using off-the shelf parts. We have used professional controls such as the RANCO ETC, standard thermostats & remote sensors, and even some questionable temperature sensors from Amazon. These have all had pitfalls, some more than others but the common one is complexity of wiring and configuration. When you are recommending a control device that is intended to last 10 to 20 years & up to the lifetime of the home, it is important to think about maintenance and usability for future occupants. ALL of the solutions up until now have been potential problems with regard to this maintenance/usability issue.

NOW, we are proud to introduce the product that we have always envisioned! The OUTDOOR AIR THERMOSTAT is an accessory for the SmartZone-4X that allows you to take full advantage of the advanced FRESH AIR features built into SmartZone-4X.

The Outdoor Air Thermostat allows you to set HIGH and LOW outdoor temperatures. Above the HIGH or below the LOW fresh-air intake will not run. In other words, you can tell the SmartZone-4X that you do not want fresh air to run when it is too HOT and/or too COLD outside.

Also, the Outdoor Air Thermostat gives you the ability to “demand” fresh air temporarily (in 5 minute increments)… AND, disable (pause) the automatic fresh air from running using the Outdoor Air Thermostat.

PLUS NOW the Outdoor Air Thermostat can be used to enable the ECONOMIZER (Free Cooling) feature on the SmartZone-4X board. Enthalpy Sensors take into account temperature & humidity to enable or disable the ECONOMIZER feature of SmartZone-4X but the cost and reliability of these types of humidity and temperature sensors can be prohibitive. The Outdoor Air Thermostat can be an affordable and effective way to utilize ECONOMIZER mode on the SmartZone-4X.
