Most smart thermostats today that are Wi-Fi enabled or have a color touch screen may require constant power through a thermostat common wire. This ensures your thermostat has a continuous flow of power to function properly. There may be a few smart thermostat models that don’t require a C wire and can operate with batteries. You should always ensure proper wiring as needed for your HVAC system and corresponding thermostat (with or without a C wire). Check your HVAC system compatibility to see if you need a C wire for your smart thermostat.

This common wire kit eliminates the need to run a new wire throughout your home. Installation is easy. Watch the videos below for more info.

For use with Sensi Smart Thermostat and Sensi Touch Smart Thermostat.
