If a Warning - Low Battery fault mes-
sage appears on the display the inter-
nal clock, calendar and program set-
tings cannot be relied on for accuracy.
Default values are loaded into the mi-
croprocessor memory and the Manual
Override key can be used to zero out
the daily schedule and allow unlimited
operation regardless of the time on the
internal clock. Reprogramming of the
setpoints and cutout values may also be
necessary. When the MANUAL OVER-
RIDE key is pressed the low battery
message will disappear. If a power fail-
ure should again occur, the above pro-
cess will again need to be repeated to
bring the chiller back on line. See also
