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).

Smart Response Technology  
This feature allows the thermostat to “learn”  
how long the heating/cooling system takes to  
reach programmed temperature settings, so  
the temperature is reached at the time you set.  
For example: Set the Wake time to 6:00 am,  
and the temperature to 70°. The heat will come  
on before 6:00 am, so the temperature is 70°  
by 6:00 am.

Glossary  
C wire  
The “C” or common wire brings 24 VAC power to the thermostat from the heating/cooling system.  
Some older mechanical or battery operated thermostats may not have this wire connection. It is  
necessary for establishing a Wi-Fi connection to your home network.  
Heat Pump heating/cooling system  
Heat pumps are used to heat and cool a home. If your old thermostat has a setting for auxiliary or  
emergency heat, you likely have a heat pump.  
Conventional heating/cooling system  
Non–heat pump type systems; these include air handlers, furnaces or boilers that run on natural gas,  
oil or electricity. They may or may not include an air conditioner.  
Jumper  
A small piece of wire that connects two terminals together.
