I purchased this thermostat because I needed to control the temperature based on a room other than where the thermostat is located. Wiring was not an issue because I was replacing another Honeywell thermostat. The programming works well, but it took me about a week to get it balanced out to my satisfaction. I was concerned that I didn't find any information in the literature about a battery backup, but after a neighborhood 2+ hour power failure, the thermostat continued to run without missing a beat when power returned.
I love my new T9 thermostat! Not only can I use remote sensors to control other rooms but I can control my home from my phone. Easy to set up, intuitive and easy to use. All in all, a great purchase!
Easy to install and use. It's plug and play if you are replacing a recent Honeywell thermostat. We replaced a T6 Pro non-WiFi thermostat that had been installed in our newly built home that was branded with the installer's name and logo which looked awful. Looks nice. Easily programmed and really like the reminder features for filter changes, etc.
Read up on the thermostat prior to deciding on this one. Went on YouTube to see how difficult of an installation process it would be. Love the thermometer, love the look and the house has been steadily comfortable since installation. Definitely recommend.
I have had this for about a month now. I have two remote sensors connected. When trying to set it up the instructions were kind of vague so had to call customer service. Even though they were having problems figuring out what I needed to do. I set it up to be adaptive but it is still not cooling the house down by the set time in the afternoon. I tried the geofence at first but unless your system is so powerful that it can change the temperature in your house in a matter of minutes it takes too long to get to the set point. I like the idea of the remotes but cannot find the usefulness of the motion sensing feature because of system reaction time.
