Check compatibility with your HVAC system before purchasing.
This thermostat is not compatible with electric baseboard heating systems.
What's a C-Wire?
A C-wire (common wire) is a low voltage power wire that many modern thermostats require for their features to work. This ecobee3 lite requires a C-wire or installation of the power extender kit (included) 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 that you have a C-wire and that your HVAC system is compatible with ecobee's thermostat. To determine if you have a C-wire, please consult ecobee’s compatibility checker. You can also hire an HVAC contractor to help you install the c-wire and the thermostat.
