This common wire (C-wire) is compatible with the Sensi™ smart thermostat and Sensi™ Touch smart thermostat. A C-wire ensures your thermostat has a continuous flow of power to function properly. Check your HVAC system compatibility to see if you need a C-wire for your smart thermostat.
This C-wire kit eliminates the need to run a new wire throughout your home.
*For the Sensi™ smart thermostat, a C-wire is required for heat only, cool only and heat pump systems. Works with HVAC equipment found in most homes and does not require a common wire (c-wire) in most applications.
For the Sensi™ Touch smart thermostat, all system types require a common wire (C-wire).
Sensi™ thermostats require a common wire to complete installation. This video will guide you in checking if you have a common wire, or an unused common wire from your previous thermostat that you can use to install your Sensi™ thermostat.
If there is not an extra unused wire running from the thermostat to the furnace, and using the G-wire as a C-wire is not an option, in most cases, installing a common wire maker kit is the best solution. Efficiency Works recommends working with a certified technician to install a C-wire to a smart thermostat to ensure safety and proper operation of your thermostat
