– Turn off power at the main service panel by removing the fuse or switching
the appropriate circuit breaker to OFF position before removing the existing thermostat.
1. Turn off power to heating & cooling system by removing the fuse or switching the appropriate circuit breaker off.
2. Remove cover of old thermostat; this should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how to install this thermostat.
Battery Installation and Information
Two “AA” alkaline batteries are used to power the thermostat. They are installed into the back of the thermostat.
Orient them in the correct direction as shown on the plastic thermostat case.
The batteries should be changed yearly to prevent leakage from damaging the thermostat and voiding your
warranty.
If the batteries are not changed the thermostat will eventually display
and conserve energy by maintaining a
lower setpoint in heating and a higher setpoint in cooling.
