Product Overview

Product Overview

Experience consistent, balanced temperatures throughout your home by utilizing the Honeywell Home T9's Smart Room Sensors. Say goodbye to rooms that fluctuate uncomfortably between too cold and too hot.

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 app — to focus on rooms based on occupancy or a specific schedule you choose. When focusing on multiple rooms, the T9 smart home thermostat works toward creating an average temperature, balancing the needs across the whole home.
