• LOW BATTERY INDICATOR — The three
"AA" alkaline batteries will maintain thermo-
stat programming for approximately one year
if power to the thermostat fails. The word
BATTERY will flash on the display if the "AA"
alkaline batteries are low and should be re-
placed. The thermostat will also make a
beeping sound every five minutes when bat-
teries need replacing. To override the beep-
ing, press any button on the keypad. The
beeping will stop for 15 hours, then start again.
You may again stop the beeping by pressing
any button on the keypad. After turning the
beep off three times, the thermostat will quit
beeping. However, you should always change
the batteries as soon as possible to ensure
that programming will not be lost in the event
of a power outage. You should also change
the batteries at least once a year.
Fresh batteries must always be installed
for millivolt systems. The heating system
will not operate if batteries are not installed
or if battery power is low.
The word BATTERY will be displayed continu-
ously (non-flashing) when 24v AC power is not
being supplied to the thermostat and the ther-
mostat is operating on battery power only.
