Installing your thermostat

Note: 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. Check the video section at wifithermostat.com

• Installing a new wire. If required, contact a contractor to install a new wire (go to wifithermostat.com to locate a contractor in your area).
