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

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.
