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 Emerson's thermostat.
For the Sensi Lite Thermostat, a C-wire is not required. Sensi thermostats are designed to work on most heating and cooling systems. Check your system and wire compatibility using the Sensi Thermostat Compatibility checker.
This thermostat is not compatible with electric baseboard heating systems.
