Description

The T9 Smart Thermostat works with Smart Room Sensors to help you adjust the temperature from anywhere and stay cozy in the rooms that matter. Place sensors where you want to see each room's temperature and humidity. Use the multi-room display on the thermostat's touchscreen — or in the Resideo app — to focus on rooms based on occupancy or a specific schedule you choose. When focusing on multiple rooms, the T9 works toward creating an average temperature, balancing the needs across the whole home.

    • YOU NEED MORE THAN 2 WIRES!
Style: Wifi Thermostat + 3 Sensors
If you have HEAT ONLY, check your existing thermostat before you buy. If you only have 2 wires, you CANNOT use this without having an electrician ($$$$) either run a new C-Wire to your furnace or using an external AC adapter plug-in. The C-Wire adapter WILL NOT WORK if you have only 2 wires. Also beware if you have zoned heat in your house - if you do, even with the C-Wire adapter, installation is going to require a professional. Honeywell, please come up with a solution here for people with no easy way to adapt for a C-wire. Batteries aren’t that complicated. ... show more

    • Regulates cold spots in house
Style: Wifi Thermostat + 3 Sensors
I love the change this thermostat and the extra sensors have made in our heat! One thermostat runs the main floor and basement but the basement was always cold. Now with the sensor, they both stay regulated. The other thermostat runs the top floor and we had a few bedrooms above the garage that were always cold. Now they are much more comfortable! You can run it on your app or alexa, I haven't set up the alexa yet. But I love the ease of the app. ... show more

    • Love this
Style: Wifi Thermostat + 3 Sensors
This system has been a lifesaver! I have a newborn and our old system would constantly go on and get freezing in the rooms…or turn off and get stuffy and hot. Since we got this system and added the temperature control prices for our rooms it has been SOOOOO MUCH BETTER!! I can adjust it from my phone, set the babies room as priority, and have the temperatures adjust based on day and night. Totally changes everything and has been wonderful with a little one. ... show more

    • Does not work if you have Humidity and outdoor temperature sensors
Style: Wifi Thermostat + 3 Sensors
This would have been great but my own system (a Carrier system) has an outdoor temperature sensor and also has a Humidistat to control my humidifier for indoor control. Both integrated into my Carrier forced air system. This Honeywell thermostat system would not integrate with either of them. Be sure to carefully check your own system to make sure the Honeywell thermostat can handle anything beyond simple heating and cooling. ... show more

    • Not freezing anymore!
Style: Wifi Thermostat + 3 Sensors
Does a great job of averaging room temperatures and keeping everyone comfortable throughout the house. We use to freeze in the bedrooms and the hallway where the old thermostat would be toasty. Not anymore thanks to the T9! Easy to install and use.
