Removing your old thermostat
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.
Note: Do not remove any wires from your thermostat at this time!
Installing Your New Thermostat
Position wall plate
Pull open the wall plate that was included with your new thermostat. Insert the bundle of wires through the back of the wall plate. Make sure at least 1/4-inch of each wire is exposed for easy insertion into the wire terminals.
Insert recommended wall anchors
It is recommended that you use the wall anchors included in the box to mount your thermostat. You can use the wall plate to mark where you want to place the wall anchors.
Connect remaining wires from Step 8
Push down on the tabs to put the wires into the inner holes of their corresponding terminals on the wall plate (one wire per terminal) until it is firmly in
place. Gently tug on the wires to verify they are secure.
Tip: If you need to release the wires again, push down the terminal tabs on the sides of the wall plate.
Close the door and mount the wall plate
Mount the wall plate using the provided screws. Install all three screws for a secure fit on your wall.
Tip: Prior to tightening the screws, use a level to ensure the wall plate is level.
