• REQUIRED: A CWire (common wire) is needed for 24 VAC power. If you do not have a CWire,
a FREE CWire Adapter offer is included.
This guide will help you determine if you have a CWire or will need to use a CWire Adapter (Step
10). The CWire is a wire that originates from your heating and cooling system and needs to be
connected to the C terminal on your thermostat. There is no universal color used to designate
this type of wire.
• Compatible with most heating/cooling, and heat pump systems
• Does not work with electric baseboard heat (120240V)

Turn off power
To protect your equipment, turn off the power
at the breaker box or switch that controls you
heating and cooling equipment.
Note: The thermostat off switch will not turn off
the power to the equipment.
Check that your system is off
Change the temperature on your old thermostat so
that your system starts heating or cooling.
If you don’t hear or feel the system turn on within 5
minutes, the power is off.
Note: If you have a digital thermostat that has a blank
display, skip this step.
Remove your existing thermostat from the wall
plate
On most thermostats, you can take off the thermostat
by grasping and gently pulling. Some thermostats
may have screws, buttons, or clasps.
Do not remove any wires from your thermostat at
this time!

Take a picture of your existing wall plate’s wiring
In order to capture all of the letters next to the
terminals, be sure to take multiple pictures from
different angles.
You may need to reference this image later.
Do you have a line voltage system?
Line voltage systems have thick black wires with
wire nuts or are labeled high voltage (120V or
higher).
Your system is not compatible. Go to
Resideo.com to find a pro installer in your
area.

Remove any jumpers
A jumper is used to connect two terminals. It may look
like a small staple or a colored wire.
Do not discard.
Keep jumpers with your old wallplate.
Label the wires
Use the stickers provided with your new thermostat to
label each wire on your existing wall plate.
Do not label jumpers. Your new thermostat does not
need jumpers.

10 Do you have a CWire?
Look at the thermostat wiring checklist from
Step 8, or the photo you took. Is the CTerminal
checked?
This means you will not need to install a
CWire Adapter. Skip to Installing Your New
Thermostat (page 13).
This means you don’t have a C-wire connected
to your thermostat. Continue to next step.

Do you have a zoning panel?
You have a zoning panel if you have multiple
thermostats and one furnace or heating system.

pro installer in your area.
Proceed to the next step.
Do you have an unused wire?
Look at the bundle of wires coming from the wall.

from the wall to find the unused wire.
