off the circuit breaker in the breaker
panel.
3. Determine Wiring
Configuration
• Remove the old thermostat from the wall to expose the wiring terminals.
• Take a picture of the wiring for future reference.
• Note the terminals attached to each wire and attach the matching label to the
ends of the wires.
Use the following table as reference:

4. Remove Old Thermostat Terminals
After all wires have been labeled, carefully
remove the wiring and any mounting or back
plate from the old thermostat.

5. Install Wiring Mount
Remove the wiring mount from the packaging, and use the included wall screws
and/or anchors to attach the wiring mount to the wall, making sure the wires run
through the center opening. If alternate mounting holes are required, use a wall
plate (sold separately).
