When unit is con®gured 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 Ð 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 speci®c 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 ¯agged 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.
