Thermostat Compatibility Guide

Please use the resources below to check the compatibility of a thermostat with your HVAC system and learn about installation.

Note: If you’ve already purchased a thermostat from the Online Marketplace and haven’t opened it yet, please verify compatibility before opening it. Returns on opened thermostats may be requested by contacting customer service but are outside of the Online Marketplace return policy. We suggest you exhaust your installation options before requesting a return.
