Installation is made easy by ecobee's [**step-by-step guide**]({openNewTab}) that can be viewed from your phone. [**Check compatibility with your HVAC system**] ({openNewTab}) 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**]({openNewTab}). You can also hire an HVAC contractor to help you install the c-wire and the thermostat.
