Product Overview

Product Overview

Control your home even when you're away with the easy-to-install T9 Smart Thermostat with Sensor. Use the multi-room display on the thermostat's touchscreen or in the Honeywell Home app to adjust the temperature based on the room's occupancy or according to a specific schedule you choose.

When focused on multiple rooms, the T9 Smart Home Thermostat will work towards creating an average temperature, balancing the needs across the whole home. Expand your T9 Thermostat system by adding up to 20 Smart Room sensors.

Whether it’s a song belted in the shower or a whispered secret, your air goes beyond simply carrying oxygen to circulating memories. Heavy or light, hot or cold, always unique to your home, the air you feel is more than its temperature setting. Our Air products and services work with you and for you, supporting and creating more comfortable surroundings.
