Before we get started you will need the following items to complete this installation:
Not the DIY Type?
Carefully remove your existing thermostat or cover from the wall. On most thermostats, you can do this by gently pulling on the device. On others, you may have to loosen screws.
*Please note that most thermostats are comprised of two parts a wall plate that is screwed to the wall and a faceplate that can be easily removed*
Plug the wires into the wall plate by pressing the clamp down on the outside while pushing the wire into the hole that corresponds with its label.
If your old thermostat is digital the screen should be blank when the power is OFF.
If your old thermostat is not-digital try changing the temperature on it. If you don’t hear the system turn on within 5 minutes, the power is OFF.
Turn off the power at the breaker box or switch that controls your heating/cooling system.
Remove each wire one at a time and label it using the supplied wire labels. If your wire has multiple designations label that wire with the additional corresponding labels
After all wires have been removed and labelled, unscrew and remove the old thermostat wall plate from the wall
