Sense the temperatures in the places that matter most with the T9 Smart Thermostat. Focus on the rooms you choose by adding Smart Room Sensors. Set a schedule or let the sensors respond to your lifestyle.

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 Honeywell Home 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.

The ENERGY STAR^® certified T9 Smart Thermostat can be programmed with a schedule or allowed to adapt to your busy life on the fly.

The Honeywell T9 Thermostat is easy to install yourself.

Note: Check your thermostats wiring compatibility before install.
