Get smart temperature control in the rooms you care about most. Choose comfort for the room you want, when you want, or allow comfort to go where you go as you move about your home. The minute your family starts waking up, your T9 Smart Thermostat starts working to get the right temperature in the rooms you want to help you prepare for the day.
With the Honeywell Home app and geofencing, the T9 will know when you're coming and going and adjust accordingly. It turns down when you leave to save energy and turns up when you arrive to keep you comfortable.
The app allows you to check in and control your thermostat from anywhere using your your phone or tablet. It also sends you alerts if something is wrong, such as an abnormally cool temperature in your home.
With Smart Room Sensors (sold separately), the T9 knows which rooms are in use so it can automatically focus on them. Intelligent motion detection algorithms help it tell the difference between someone passing through or spending time in a room, so your ideal comfort can efficiently follow you from room to room.
As everyone settles in for the night, the T9 shifts focus to the rooms which you selected as important to look after so everyone's sleeping temperature is just right.
The Honeywell Home T9 Smart Thermostat is compatible with most heating, cooling, and heat pump systems.
The T9 does NOT work with the following:
Please note a C-Wire (common wire) is needed for 24 VAC power. If you do not have a C-Wire, then a C-Wire Adapter is provided. More information on C-Wires can be found in the installation manual below.
The T9 pairs with Samsung Smart Things, Apple Home Kit, and the Google Assistant for voice control.
