The box claims HomeKit comparability but the T9 doesn’t support it. Also, unlike many other thermostats, there’s no faceplate available to cover larger previous installation.
Relatively easy to install. And it works. No more running around try to adjust the thermostat to compensate for temperature differences in different rooms
I'm a retired HVACR,Thru the years, I have worked with many types of Controls. I believe Honeywell is a leader in temperature controllers, I upgraded my home from a T6 to the T9 with three sensors. I like T9 thermostat. It preforms well. I use the follow me sensor method
This product was recommended over any others that are out there. I was skeptical at first but decided because Honeywell is the #1 in cooling and heating thermostat, why not give it a try. I was very impressed by the price and product works outstanding with my unit’s. I did buy the second one after trying the first one for a month. I am glad I took my AC technician’s advice. They also came with sensors to place in other rooms. I highly recommend you try this Honeywell product.
