Installation

Before You Buy: Check if Your Equipment is Compatible

What is a C-Wire?

A C-wire (common wire) is required for most HVACs. A C-wire is a low voltage power wire that many modern thermostats require for their features to work. Many older homes don’t have a C-wire because mercury and battery-powered thermostats didn’t require one. Therefore, it is important that you make sure your HVAC system is compatible with Sensi's thermostat.

For the Sensi Classic Thermostat, a 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. Check compatibility with your HVAC system before purchasing. You can also hire an HVAC contractor to help you install the C-wire and the thermostat.

This thermostat is not compatible with electric baseboard heating systems.
