OVERVIEW
The schedule screen contains more programmable val-
ues than a normal display screen. As such, each pro-
grammable value is not linked to a specific button. In-
stead the
Select
key is used to enable the cursor arrows
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 "
" (
Check
) key to program the Start /
Stop times for that day.
In order for the Start / Stop combination to be uti-
lized, each Start time must have a corresponding 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 12:00 AM.
If the Start time equals the Stop time (with any time
other than 12:00 AM), 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 define 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 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 6
th
week
slot.
DISPLAY ONLY
This screen displays the chiller schedule. There are no
other display options.
