SmartZone 4x Smart Zone Control 4 Zone Controller Kit w/Temp Sensor Universal Replacement for Honeywell Zoning Panel Truezone HZ432 & More by Smart Zone

Our 3 zone heating system was about 22 years old, and all of the thermostats were pretty ancient. It was quite a task to simply change the temperature settings on the old touch screens. I wanted to upgrade to smart thermostats, and I saw a good price for EcoBee 3 Lite thermostats from my electricity provider, and decided to try installing them myself. I quickly realized that the EcoBee thermostats would not work on the current system configuration, that is, a master thermostat and the other two subservient. Also, two of the dampers were compatible with the thermostats, but the one associated with the master was not. I got my favorite HVAC people to replace the incompatible damper with one compatible with the thermostat. Then, the fun started. Before taking pulling out the wires from the old control panel, I made sure I knew what each wire was connected to...thermostat, damper, AC, blower. I began to realize that the color of the wires was not consistent, so I had to label each wire identifying the thermostat, damper, whatever, and the connectors in each. Next I took pictures of all the connections into the control panel. I spent a lot of time on the EcoJay web site to understand how my wires would be connected to the new EcoJay board. If I had any questions, the customer service people were able to help me, and gave me a feeling that I could count on them if I hit any snags. I used some 3-M double sided mounting tape to mount the EcoJay beside the old control panel and took one wire out of the old and into the new. Since the old thermostats used just a few wires whereas the new EcoBees used five, I happily discovered that the original installers had left extra wires to work with. I got all the expected wiring done in about an hour, and then spent more time checking the wiring diagrams that came with the EcoJay panel, and with the pictures I took earlier. I was then able to remove the old panel. Once I installed the three EcoBee thermostats, I was ready to turn on the power. Almost everything worked perfectly, especially the EcoJay and EcoBee components. The only problem I had was that the original installer had mis-wired the basement damper. We now have had the EcoJay running for more than a year, and I'm thrilled with the device. It was far less expensive than the panels the local HVAC people wanted to install, and I've gained an understanding of how the system works. I highly recommend the EcoJay if you want to do the installation yourself. It was easy, and as I stated above, the help I got from the EcoJay customer service people gave me confidence I could do it.

Wow! This is one excellent product. I spent several days struggling with an old Duro Dyne controller, finally got document from the factory archives only to discover my cooling output was bad. I began a search for a replacement 4 zone controller, not having high hope of getting something quickly. Well….turns out this does everything the Duro Dyne controller did and much more, for a very reasonable price, and it arrived in just 2 days. Installation was very easy, and the controller is just awesome. Cudos to the design team for putting LEDs on every input and output…with color matching the function. That just genius! I could not be happier with my purchase!

I had a 20 year old Carrier Zone controller on its last legs. I bought this Ecojay SmartZone-4X controller to replace the old one at the point I upgraded the furnace and cooling condenser. Before I bought the EcoJay product, I called in to verify that it would work with my equipment. I got a slow, detailed, thorough discussion, and decided to buy it. After my new HVAC equipment was installed, I installed the zone controller. The product does exactly what the sales literature says it will. I've had it in use for about a month, and it's performed flawlessly. This controller board is exceptionally well-designed and manufactured. It's easy to install, and the documentation is easy to follow. The board has LED lights on it and digital displays that tell you exactly what the board is doing, making it a snap to diagnose problems and monitor the board's performance during the test-out phase of installation. The post-sale support is exceptional on all counts. Fast, competent, patient, free. I am not an HVAC professional, and I made two mistakes during installation which would have ruined a less-well-designed board. I called EcoJay's support line, and they helped me fix my problems in minutes. I recommend this product with no reservations.

I don't write many reviews. However, I feel I need to about this product and customer support. The system was very easy to wire up. Pretty Self explanatory. Directions were straight forward and easy to understand. However, I did have an issue but not with the ECOJAY System.. It was me being "A MAN" and not fully reading the instructions on the Thermostats I bought. Thinking I had everything correct.. I called ECOJAY support.. AMAZINGLY an actual person answered the phone and I didn't have to press 1 for English etc... I Immediately was talking with Jeff, Tech Support. Jeff was very helpful and knowledgeable of not only his product by other products as well.. He walked me through some troubleshooting to be sure what he knew what the issue was. My "Failure" to read and follow the Settup of the Thermostats was the issue. Jeff was very friendly and helpful. Thank you Jeff...

As an HVAC contractor this is not my normal brand that I like to use. HOWEVER, when you’re in a pinch and Amazon delivers next day on a weekend it’s a fantastic option!! 😂😂😂😂 The instructions are easy to read, it was compatible with my system and dampers, and delivered on a Sunday what more could you ask for! Great replacement option if you do t have access to an HVAC supply house.
