schedule.
If the chiller is not required to run on a given day, the

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.
After the Enter key is pressed, a display to designate
which days of the week are holidays will appear:
*
S
M
T
H O L I D A Y
N O T E D
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 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 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.
