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.

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.
Note: System setting function 13 controls

Heat and cool settings must be at least
3 degrees apart. The thermostat will

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.
MAC ID, MAC CRC
Alphanumeric codes that uniquely identify your thermostat.
QR Code®
Quick response code. A two-dimensional,machine-readable image. Your wireless device can read
the black and white pattern in the square and link its browser directly to a web site. QR Code is a
