When unit is configured for dual set point, chilled liquid
pump relay is energized continuously, in both occupied and
unoccupied modes. Occupied mode places occupied chilled
water set point into effect; unoccupied mode places unoc-
cupied chilled water set point into effect.
Scheduling —
is used to override any current sched-
ule in effect (for 0-4 hours).
is used to activate a
clock for the scheduling function.
-
are used
to program schedules for specific occupied and unoccupied
periods.
The schedule consists of from one to 8 occupied time pe-
riods, set by the operator. These time periods can be flagged
to be in effect or not in effect on each day of the week. The
day begins at 00.00 and ends at 24.00. The machine is in
unoccupied mode unless a scheduled time period is in effect.
If an occupied period is to extend past midnight, it must be
programmed in the following manner: occupied period must
end at 24:00 hours (midnight); a new occupied period must
be programmed to begin at 00:00 hours.
