Installing Batteries
IMPORTANT
Batteries are required only for
armchair programming and to retain
your personal temperature schedule
in memory if ac power is lost.
• Use two AA alkaline batteries; nonalkaline
batteries do not last as long. We recom-
mend Energizer® batteries.
• Make sure the thermostat is set to the OFF
position.
• Use a coin to remove the battery door.
