temperature with your current thermostat and wait for at
least 5 minutes to be sure that the system is OFF.
Step 1
Ensure the system is off
Step 2
Confirm that your system is turned off by turning off heating mode (winter) or cooling mode (summer).
Wait for a few minutes until you can't feel any air coming out of the vent.

press them together.
· Pull the wires trough the hole in the middle of the wall plate and attach the wall plate to the wall by
