To install the thermostat:
1. Gently separate the backplate from the thermostat.
2. Place the thermostat backplate on the wall. Make sure that
any existing wires can be inserted through the opening on the
thermostat.
3. Using the backplate as a template, mark the location of the
mounting holes on the wall as shown below.

ensure the thermostat can be mounted securely to the wall.
