Schedule screen
Figure 30: Schedule screen
The schedule screen contains more programmable values than a normal display screen. Each
programmable value is not linked to a specific button. Instead the Select button is used to enable
the cursor arrows, which are used to highlight the day and the start or stop time the user wants to
modify. At this point the user may press the Enter ( ✓ ) button to program the start and stop times
for that day.
The user can define a standard set of start and stop times that are used every week. The user
can then specify exception start and stop combinations for any day of the week up to six weeks
in advance. At the end of each week, the schedule for the next week is created by combining the
standard week definition and the next defined exception week. The schedule is then updated as
each of the exception weeks shifts down, leaving a new, blank exception week in the sixth week
slot.
This screen displays the chiller schedule. There are no other display options.

Button Access Description
Standard Week Start/Stop
Times
Operator For each day of the week, the user may specify a time for the chiller to start
and a time for the chiller to stop. The times specified in this entry week will
be used as the default for every week of chiller operation.
Exception Start/Stop Times Operator For each day of the week, the user may specify a time for the chiller to start
and a time for the chiller to stop. These start and stop combinations may be
scheduled up to five weeks in advance and also for the present week. As each
week goes by, the new schedule will be created for the present week using
the Exception specification in combination with the Standard week definition,
as described above.
Schedule (Enabled / Disabled) Operator Allows the user to enable or disable the monitoring function which enforces
the scheduled starting and stopping of the chiller.
Repeat Sunday Schedule Operator Duplicates the schedule defined for Sunday for the remainder of the
standard weekdays.
