Had a new home built with Honeywell, installation was a breeze. Popped off the original and popped on the new T9. Easy to set up and control from my phone.
This thermostat is providing us functionality, economy and peace of mind as we use it to control and monitor our vacation house while we are not there.
Overall I like it. The display needs to show what stage the unit is operating in. My t4 showed heat or cool on, fan on when operating. This unit and the app needs to do so as well. An included wall mount would have been nice. This unit is a different size than the t4 so it looks strange attached to the t4 mount. A t6 Wi-Fi would have been a better purchase.
It’s almost great. With three sensors, our home has never been more comfortable. What is missing is a fan/air circulating option that detects when a room is too warm, or cold, then turns on the fan to try to normalize the temperatures.
So good, and so easy. I had the earlier Honeywell smart thermostat, but this one has app support. I also like the external room sensors. Traditionally cooler rooms can be more comfortable when using them.
