SmartZone-2X : 2 Zone HVAC Controller KIT w/ Temp Sensor; Dual climate control to replace Honeywell, EWC, Zonefirst, Zonex, Durozone & more by ECOJAY SmartZone

Easy to install and set up. I installed dampers in my house and two new thermostats. I bought this board for the control and I love it!

This is a fantastic product. Works so well and the support is so good. Jeff from eco jay was amazing and very responsive. 100% recommend

I discovered the SmartZone 3.0 while researching a replacement for my old Honeywell MiniZone system. I had never heard of Ecojay before, so I checked online reviews and noticed that users seemed very satisfied. I decided to give it a try and installed the board myself. Even though I’m not an HVAC expert and this was my first time installing a zoning board, the setup went smoothly. Many of the issues I ran into turned out to be furnace-related, which I later resolved. During the installation, I emailed the seller multiple times with basic questions, and they responded quickly—often the same day. The SmartZone 3.0 is well-designed, intuitive, and in my opinion one of the best zoning boards available. It is well priced and really easy to install. It clearly shows what your furnace and dampers are doing in real time, which makes troubleshooting much easier. Excellent product and outstanding support. Highly recommend.

We moved into our current home six months ago and decided to call a HVAC tech to come and look at our furnace and give it a once over. He cleaned it and was on his way. We woke up the next morning without heat. The HVAC tech came back within two hours and told us our zone panel was not communicating with the furnace anymore (it was old) and his company wanted $2600 to redo the zone system. He did bypass the zone panel and just communicated with the one thermostat. I told them I would look elsewhere for a solution. I looked for systems online that would be compatible with my current setup, which is a two-zone. Naturally I found the upgrade to what I had, which was the honeywell Trol-a-temp. But I also found the Ecojay on Amazon, and I was interested. I studied many reviews for this and looked at the pictures, manual, YT videos, and I decided to pull the trigger and go ahead and do it myself. The overall good reviews and knowing that the customer service was very good was enough for me to try it. I noticed from the reviews that a dedicated transformer would be needed, so I bought one of those too. It was not very clear in the description of the item, but it does also say in the manual one is needed. I didn't realize our furnace already had a dedicated transformer wired in for the zone panel already. Overall, it was very easy to move the wires over. The only tricky thing for me was knowing what order the wires needed to be for the dampers. The trol-a-temp is labeled horribly so I decided to go by the order in which the manual had the wires. I plugged it in to the existing transformer and it lit up perfectly. I was excited! The furnace communicated with the panel very well and so did the thermostats. About ten minutes later, the transformer started smoking terribly and then the Ecojay board only lit up two lights for the Equip connection. Oh no, I thought. Did I blow the board? I was thankful I was present when it started smoking. I can't get the Ecojay to respond. I tried my backup transformer plug I had purchased and that did nothing either. I gave up and thought I would call support on the following Monday. I decided to attack it again the next day. I found an old manual online for my Trol-a-temp and read for awhile and noticed I possibly had the wires wrong for the dampers in the ecojay. I rearranged the wires for the dampers, plugged it back in to the plug transformer, and the board lit back up! I was relieved. The incorrect wire placement for the dampers must have overloaded the transformer. After a few days, the board has been working perfectly. I love all of the lights and how they tell you exactly what is going on and what with each thermostat. The manual explains all of the lights and what process is going on at that moment very well. Overall, I think this is an excellent alternative from the big brand. The documentation is very good to DIY and from my understanding, the customer service is the best. You won't get that with the other brand.

J'ai acheté ce contrôleur Ecojay pour remplacer un Honeywell qui avait seulement 2H et 2C vs le Ecojay qui peut faire 3H et 2C. J'ai contacté Jeff au Texas de la Cie Ecojay et Jeff m'a donné le meilleur service àa la clientèle à vie au téléphone. Les instructions sont également super clairs. Ma thermopompe Lennox 2 stages fonctionne vraiment mieux depuis le upgrade du Ecojay
