Installing your thermostat

Important! The Wi-Fi thermostat requires a C wire to operate. The C, or common, wire

brings 24 VAC power to the thermostat. Many older mechanical or battery operated thermostats do not require a C wire. If you don’t have a C wire, try:

• Looking for an unused wire that is pushed into the wall. Connect that wire to C and check that it is connected to the 24 VAC common at your heating/cooling system.

Note: Not all heating/cooling systems label the 24 VAC common C. Check your system

manual or contact the manufacturer to find out which terminal is the 24 VAC common.
