The T9 senses the temperatures in the rooms you care about most. Focus on the rooms you choose as a part of your set schedule, or allow comfort to go where you go as you move about your home. Then, help save energy when you leave.

Place Smart Room 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 app to easily focus on rooms either based on their occupancy or according to a specific schedule you choose.

When focused on multiple rooms, the T9 will work towards creating an average temperature, balancing the needs across the whole home.

Purchase the T9 bundled with a sensor, and expand the system by adding up to 20 additional sensors.

With the Honeywell Home app, using geofencing the T9 knows when you’re coming and going, so no matter your schedule, you can always come home to comfort and save energy when you’re away.

The T9 learns your home’s heating and cooling cycles to help deliver the optimal temperature at the right time. Plus you can be alerted when it’s time to change your filters and when temperatures get too high or low.

It’s easy to incorporate the T9 into your home system. Our partners integrate through the Works with Honeywell Home program so you can control your devices the way you want.
