The T9 thermostat is easy to install and setup. With the Resideo app you can remotely control the temperature of your home to suit your comfort. Has a huge and bright display screen. Temperature sensors can be added to control the temperature in any chosen room.
I purchased this smart thermostat after researching many different units and I landed on this one. I have been nothing but pleased! The format of the thermostat is great and very user-friendly. It has all of the features that you could ask for, I would highly recommend!
This thermostat does everything you would want to keep your house warm or cool whether you’re home or not. Combine it with the room sensors and it makes this thermostat even better. I’ve owned 2 of these in 2 different homes now…. Better than a NEST or anything else out there IMHO.
The home we just bought has a whole home control system. The previous owner left leaving no instructions or documentation. It controls lighting, door locks, TV, radio, home theater, AND 5 zones of hydronic heat. I didn't care so much about all the other stuff but really needed to be able to program and control the heating in the house. I even called an ELAN rep out to help decipher. He had no luck. So I began replacing the zone control with the Honeywell T9. Bought only one at first. If I failed, I'd return it. But I didn't fail. It took a little extra wiring to get a common to the thermostat. Then, VOILA! It sprang to life. Without the manual, I began to program it. Easy peasy. At least one more zone needs control so I bought the 2nd one.
Now, 2 months later, there's no need for heating up here in the mountains. But the cold will be back. And that's when I'm going to buy two more T9 thermostats for the rest of the zones.
