What is the difference between T9/T10 Pro Smart Room Sensors and a zoned HVAC system?

The T9 and T10 Pro Smart Thermostat uses up to 20 wireless sensors to read temperatures in multiple rooms of your home. Based on your preferences, the thermostat can read from, and average, these multiple sensors and the thermostat. The T9 and T10 Smart Thermostat will calculate the average of the temperatures detected in all selected or active rooms to deliver the best temperature to your whole home. In this way, the T9 and T10 Smart Thermostats work with the sensors to make you feel closer to your desired temperature, wherever you are in the home.

While the T9 and T10 thermostat can better fine-tune your comfort in your home, it’s important to distinguish that no thermostat alone, regardless of sensors, can maintain separate temperatures in different rooms without air dampers or smart vents. Honeywell Home provides a true zoning solution that can be purchased through a professional contractor.

For homes that already utilize a zoning solution, such as a zone control board or duct dampers, Smart Room Sensors can still help further increase comfort and savings by providing a more accurate reading of the temperature in each zone. A T9 or T10 Smart Thermostat would be required for each zone being controlled, and each thermostat will require its own sensors, based on your desired level of control. Smart Room Sensors cannot connect with more than one thermostat.

If you have any questions about whether or not the T9 and T10 Smart Thermostat is the best option for your home, you can contact our support team or find a local pro.
