8.3 SET SCHEDULE/HOLIDAY KEY
Messages showing each week day and the holiday start/
stop schedule, as shown below, can be displayed using
the ‘SET SCHEDULE/HOLIDAY’ key:
The displays for each day are scrolled through by re-
petitively pressing the ‘
á
’ or ‘
â
’ key.
To reprogram any of the daily schedules, key in the
new start time then, if necessary, change the associated
AM/PM by pressing the ‘
á
’ or ‘
â
’ key.
The ‘
á
’ or ‘
â
’ key can only be pressed
once to change ‘AM/PM’. If an error
is made, press ‘CANCEL’ and begin
again.
Next key in the stop time (the cursor will automati-
cally skip from ‘AM/PM’ to the first digit of the date
when a ‘number key’ is pressed) and change the AM/
PM if necessary.
Now press the ‘ENTER’ key to store the new sched-
ule. The display will scroll to the next day.
If an unacceptable time is entered, the following mes-
sage will be displayed for 3 seconds then return to the
schedule display:
New start/stop times programmed for
Monday are automatically used for all
following days of the week.
Always use the ‘SET SCHEDULE/
HOLIDAY’ key, not the ‘ENTER’ key
to scroll through the schedule displays.
Pressing the ‘ENTER’ key after view-
ing Monday will change times pro-
grammed for the remainder of the
week to the Monday schedule.
If the chiller is not cycled by the ‘DAILY SCHEDULE’,
but is required to run whenever remote cycling devices,
system switches, and the chiller ‘ON/OFF’ switch are
in the ‘ON’ position, all ’00.00’s should be programmed
into the daily schedule. This can be done manually for
individual days or for all days by pressing ‘CANCEL’
and ‘ENTER’ for the Monday start/stop schedule.
Programming the ‘DAILY SCHED-
ULE’ will not affect on the ‘HOLIDAY
SCHEDULE’.
If the chiller is not required to run on a given day, the
start time should be programmed for ‘00:00 AM’ and
the stop time programmed for ‘12:00 AM’.
Continue to program each day as needed. After ‘SUN’
(Sunday) has been entered, the Holiday message will
be displayed:
The ‘HOLIDAY SCHEDULE’ allows a specific day(s)
to be assigned for special requirements. This is pro-
vided so that a day(s) needing special start/stop require-
ments can be programmed without changing the nor-
mal working schedule.
The start/stop times for the ‘HOLIDAY SCHEDULE’
are programmed just as any other day.
Only one start/stop time can be pro-
grammed which will apply to each
of the holiday days selected.
After the ‘ENTER’ key is pressed, a display to desig-
nate which days of the week are holidays will appear:
When the display appears, the cursor will first stop af-
ter ‘S’ (Sunday) as shown. To designate a day as a holi-
day, press the ‘*’ key. If a day marked as a holiday is
not to be a holiday, press the ‘*’ key.
When the ‘*’ key is pressed, the cursor will advance to
