Changing Batteries
IMPORTANT
Batteries are required for program-
ming and operation of the thermostat
and heating/cooling system.
As the batteries run
low,
bAt Lo
indicator
flashes
for one
to two
months
before
the batteries
run out com-
pletely. Replace the
batteries as soon as
possible after the indicator starts flashing. If
you do not replace the batteries when the
indicator light is flashing
bAt Lo, the indicator
stops flashing. When the batteries are almost
completely dead, bAt
Lo stays on without
flashing to indicate the thermostat and heating/
cooling system have stopped working.
After the batteries are completely dead, the bAt
Lo indicator disappears, leaving a completely
blank display.
•
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.
