Maintaining Your Thermostat

Installing Batteries

IMPORTANT
Batteries must be installed for program-
ming and operation of the thermostat
and heating/cooling system.
Purchase two AA alkaline batteries; non-
alkaline batteries do not last as long, and
can leak causing damage to the thermo-
stat or wall surface. We recommend
Energizer® batteries.
Make sure the thermostat is set to the
OFF position.
Use a coin to remove the battery door.
Install the fresh batteries, making sure
positive and negative terminals are
oriented correctly.
Replace the battery door.
