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 has
been entered, the Holiday message will be displayed:
The Holiday (HOL) Start / Stop allows a specific day(s)
to be assigned for special requirements. This is provided
so that a day(s) needing special start / stop requirements
can be programmed without disturbing the normal
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.

which days of the week are holidays will appear:
When the display appears, the cursor will first stop
after 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

or


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 Schedule (MON).
The Holiday Schedule is only per‑
formed once, then erased from memory.
This avoids the need for reprogram‑
ming after the holiday, as most special
Holiday Schedule requirements are
occur only occasionally.
The displays for each day are scrolled through by re-
petitively pressing the


once to change AM/PM. If an error is
made, press Cancel and begin again.

skip from AM/PM to the first digit of the date when a
“number key” is pressed) and the AM/PM if necessary.
Now press the ENTER key to store the new schedule.
The display will scroll to the next day. If an unacceptable
time is entered, the following message will be displayed
for 3 seconds then return to the schedule display:
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 schedule displays. Pressing the
ENTER key after viewing Monday
will change times programmed 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 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
individual days or for all days by pressing Cancel and
Enter for the Monday Start/Stop schedule.
