SCHEDULE SCREEN
OVERVIEW
The schedule screen contains more pro gram ma ble val ues
than a normal display screen. As such, each pro gram -
ma ble value is not linked to a speciÞ c but ton. In stead the
Select key is used to enable the cur sor ar rows which
are used to highlight the day and the start or stop time
the user wishes to modify. At this point the user may
press the ‘! (ENTER) key to pro gram the Start / Stop
times for that day.
In order for the Start / Stop combination to be utilized,
each Start time must have a cor re spond ing Stop time
which occurs later in the day. The presently pro grammed
schedule for a given day can be cancelled by setting
both the Start time and Stop time to 12:00AM. If the
Start time equals the Stop time (with any time other
than 12:00AM), the chiller is OFF for that day. If the
user desires the chiller to operate continuously through
several days, the Stop time of Day 1 can be set to 11:
59 PM and the Start time of Day 2 can be set to 12:00
AM. The chiller will not stop but continue to operate
until the stop of Day 2.
The user has the ability to deÞ ne a standard set of Start /
Stop times which are utilized every week. The user may
then specify exception Start / Stop combinations for any
day of the week up to 6 weeks in advance. At the end
of each week the schedule for the next week is created
by com bin ing the standard week deÞ nition and the next
de Þ ned exception week. The schedule is then updated
as each of the exception weeks “shifts down”, leaving a
new, blank exception week in the 6
th
week slot.
