Programming the DAILY SCHED ULE
will not affect the holiday sched ule.

If the chiller is not required to run on a given day, the
Start time should be pro grammed for 00:00 AM and the
Stop time pro grammed for 12:00 AM.

Continue to program each day as needed. After SUN has
been entered, the Holiday message will be dis played:

The Holiday (HOL) Start / Stop allows a specifi c day(s)
to be assigned for special requirements. This is pro vid ed
so that a day(s) needing special start / stop re quire ments
can be programmed without disturbing the normal work-
ing schedule. The start / stop times for the Holiday sched-
ule are pro grammed just as any other day.

Only one start/stop time can be pro-
grammed which will apply to each of
the Hol i day days selected.

After the Enter key is pressed, a display to designate
which days of the week are holidays will ap pear:

When the display appears, the cursor will fi rst stop af-
ter Sunday as shown. To designate a day as a holiday,
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 the next day. Use
the

keys to move back and forth among days.

After all the holiday days are programmed, press Enter
to store the new data. The display will then return to the
beginning of the Daily Sched ule (MON).

The Holiday Schedule is only executed
once, then erased from mem o ry. This
avoids the need for re pro gram ming
after the hol i day, as most special Holi-
day Sched ule re quire ments occur only
oc ca sion al ly.

The displays for each day are scrolled through by re-
pet i tive ly pressing the set Schedule/Holiday key. To re-
program any of the daily schedules, key in the new Start
time then, if necessary, change the associated AM/PM
by pressing the

key.

The

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 au to mat i cal ly
skip from AM/PM to the fi rst digit of the stop time when
a “number key” is pressed) and the AM/PM if nec es sary.
Now press the ENTER key to store the new sched ule.
The display will scroll to the next day. If an un ac cept able
time is entered, the following message will be displayed
for 3 seconds then return to the schedule dis play:

New start/stop times programmed for
Monday are automatically used for all
of the following days of the week.

Always use the Set Schedule/Holiday
key, not the Enter key to scroll through
the sched ule displays. Pressing the
ENTER key after viewing Monday
will change times programmed for the
re main der of the week to the Monday
schedule.

If the chiller is not cycled by the Daily Schedule, but is
required to run whenever remote cy cling devices, sys tem
switches, and main Chiller ON/OFF switch are in the
ON position, all 00.00s should be programmed into the
daily schedule. This can be done manually for in di vid u al
days or for all days by pressing Cancel and En ter for the
Monday Start/Stop schedule.
