Operating instructions

26
Two Internal Time Schedules are available and must be
field programmed. Time Schedule 1 (SCH1) is used for single
set point On-Off control. Time Schedule 2 (SCH2) is used for
dual set point On-Off and Occupied-Unoccupied set point con-
trol. The control will use the operating schedules as defined un-
der the Time Clock mode in the Navigator display module.
The schedules consist of 8 user-configurable occupied time
periods. The control supports time schedules for local control,
remote control, and ice building. 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, the occupied
period must end at 24:00 hours (midnight) and a new occupied
period must be programmed to begin at 00:00 hours.
In the following example, a early morning pulldown time
period is scheduled for Monday morning from 12:00 AM to
3:00 AM. The occupied period starts at 7:00 AM, Monday
through Saturday. The occupied time ends at 6:00 PM on Mon-
day and Tuesday, 9:30 PM on Wednesday, 5:00 PM on Thurs-
day and Friday, and 12:00 PM on Saturday.
NOTE: This schedule was designed to illustrate the program-
ming of the schedule function and is not intended as a recom-
mended schedule for chiller operation.
If the chiller is to be controlled to a single set point, use
Schedule 1 (SCH1). This type of schedule will start and stop
the machine only. During the unoccupied times, the chiller will
be off. If the chiller is to be controlled to 2 set points, occupied
and unoccupied, use Schedule 2 (SCH2). This will cause the
chiller to control to an occupied set point and an unoccupied set
point. The machine will be able to provide cooling at any time.
To configure this option while using the Navigator™ dis-
play, see Table 22.
Holiday Schedule
— The unit control allows up to 16 holiday
periods. All holidays are entered with numerical values. First
enter the month (MON.x), then the day (DAY.x), then the
duration (DUR.x) of the holiday period in days. If a holiday in
included in one of the Occupied Time Periods of the schedule,
the machine will follow that operating condition for the
holiday. In the following examples, the holidays July 4 and
December 25-26 are programmed for Holiday 1 and Holiday 2
respectively.
To configure this option for the Navigator display, see
Table 23.
CCN Global Time Schedule
— A CCN global schedule can
be used if desired. The schedule number can be set anywhere
from 65 to 99 for operation under a CCN global schedule. The
30XA chillers can be configured to follow a CCN Global
Time Schedule broadcast by another system element. The
ComfortVIEW™ Network Manager’s Configure and Modify
commands or the Service Tool’s Modify/Names function must
be used to change the number of the Occupancy Equipment
Part Table Name (OCC1P01E) to the Global Schedule Num-
ber. The Schedule Number can be set from 65 to 99
(OCC1P65E to OCC1P99E).
