COMPATIBILITY

Before you purchase the Sensi Smart Thermostat, please make sure that your heating and cooling system(s) are compatible. You can easily check your HVAC compatibility by using our thermostat buyer's guide.

C-wire is required for most HVACs

A c-wire (also referred to as a common wire) is a low voltage power wire that many modern thermostats require for their features to work.

For Sensi Wi-Fi Thermostat, a common wire (c-wire) is required for heat only systems, cool only systems and heat pump without auxiliary heat. Two AA batteries (included) provide backup power that can last for months. However, if you have a c-wire, it is recommended that you connect it.

If you still have any questions regarding the Sensi Thermostat, please contact our customer support team.
