The Low Battery Warning can only occur at unit pow-
er-up. On micro panel power-up, the RTC battery is
checked. If a low battery is found, all programmed
setpoints, program values, options, time, schedule, and
history buffers will be lost. These values will all be re-
set to their default values which may not be the desired
operating values. Once a faulty battery is detected, the
unit will be prevented from running until the PRO-
GRAM key is pressed. Once PROGRAM is pressed
the anti-recycle timers will be set to the programmed
anti-recycle time to allow the operator time to check
setpoints, and if necessary, reprogram programmable
values and options.

If a low battery is detected, it should be replaced as
soon as possible. The programmed values will all be
lost and the unit will be prevented from running on the
next power interruption. The RTC/battery (031-02565-
000) is located at U5 on the IPU microboard (031-
02630-000).
