Once the desired information is keyed in, it may be
stored in memory by pressing the ENTER key. After
the ENTER key is pressed, the cursor will move under
the “T” of TODAY.
The micro will accept any valid time or date. If an out
of range value is entered, the micro will display the
following message for 3 seconds before it reverts back
to the SET TIME display message to let the user know
that another try at reprogramming is necessary.
PROGRAMMING THE DAILY START/STOP AND
HOLIDAY SCHEDULE
Set Schedule/Holiday
Messages showing the start/stop schedule of each day
of the week as well as the holiday start/stop schedule
can be displayed after the SET SCHEDULE/HOLIDAY
key is pressed. The display can be scrolled through
day-by-day simply by repetitively pressing the ENTER
or ADVANCE DAY key. A typical daily schedule display
is shown below:
To reprogram any of the daily schedules, key in the
new START time. To change the AM/PM associated
with the START time, press the “AM/PM” key. This will
change the AM/PM message to the opposite time pe-
riod. The “AM/PM” key can only be pressed once. If an
error is made, press CANCEL and begin reprogram-
ming again.
After the START time and the associated AM/PM have
been programmed, the cursor will move to the STOP
time. Key in the STOP TIME and press the “AM/PM”
key if AM/PM requires changing.
When the ENTER key is pressed, the new START/
STOP time is entered and the display will scroll to the
next day. If an unacceptable time is entered, the follow-
ing message will be displayed.
For ease of programming, any values “ENTERED” for
MONDAY will automatically be put in for the other days
of the week. Be aware of this any time the MONDAY
SCHEDULE is changed, since it changes times previ-
ously programmed into other days. For scrolling through
the days to view times programmed use the ADVANCE
DAY KEY, not the ENTER KEY. This will assure that
after viewing MONDAY, that the ENTER KEY is not
pressed changing times programmed for the rest of
the week.
If the chiller is not cycled by the DAILY SCHEDULE,
but is required to run whenever the system switches
are on, all 00.00’s should be programmed into the daily
schedule. This can be done manually for each day or
by pressing CANCEL and ENTER when the MONDAY
START/STOP schedule appears.
NOTE: This will have no effect on the holiday schedule.
Continue to program each day as needed. After MON
through SUN has been entered, the HOLIDAY mes-
sage will be displayed.
The Holiday (HOL) START/STOP allows the user to
designate a specific day(s) for special requirements.
This is provided so that day(s) needing special start/
stop requirements can be programmed without disturb-
ing the normal working schedule.
The start/stop times for the Holiday schedule are pro-
grammed just as for any other day.
NOTE: Only one start/stop time can be programmed
which will apply to each of the “HOLIDAY” days
selected.
After the ENTER key is pressed, a new message will
be displayed to designate which days of the week are
to be holidays.
In the above sample display, an * designates Tuesday
as a holiday.
When the display appears, the cursor will first stop
behind Sunday. To designate a day as a holiday, press
the “*” key. If a day is not to be a holiday, press the “0”
key. Whenever the “*” or the “0” keys are pressed, the
cursor will advance to the next day. After all the holiday
days are programmed, press ENTER to store the new
data into memory. The display will then advance to the
beginning of the Daily Schedule (MON).
The Holiday Schedule is only executed once by the
micro before it is erased from memory. This is done
because in most cases a special Holiday Schedule is
