• 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.
