Most Wi-Fi thermostats have enhanced features such as Wi-Fi radios and LED color screens that require the unit be powered at all times. Thermostats can get this constant power through a common wire c-wire. If you do not have a c-wire at your thermostat or in your furnace, the Emerson thermostat common wire kit allows you to reconfigure your existing wires without needing to run a new wire throughout your home.
No c-wire, no problem – this common wire kit eliminates the need to run a new wire throughout your home
Easy solution when running an additional wire is not an option
Easy installation process – refer to our videos and installation guide for step-by-step instructions
Does not work with 2-wire systems
For use with Sensi Wi-Fi thermostat and Sensi touch Wi-Fi thermostat
