Remove Old Thermostat

instructions carefully. Wires must be labeled prior to removal.
IMPORTANT! Turn off the power to the HVAC system at the mainpower panel or at the
HVAC system.
Remove existing thermostat cover and thermostat. See Figure 1. Some thermostats will have
screws or other locking devices that must first be removed. Once the wall mounting plate is
exposed, look for wires.
If wires are not visible, they may be connected to the back of the wallplate. Again, look for
screws, tabs, etc. Some models have doors that open to expose wires and mounting screws.
