Step Action
1 While not in any Set Point routine, press
the SET button once and observe
"PRESSURE SET UP" in the display.
(NOTE: If you press SET more than once,
the display will cycle through the Pressure
Set Up Set Points. Continue pressing SET
and stop with the display showing
"PRESSURE SET UP").
2 Press the Right Arrow button four times,
observe "ROTATION SET UP" in the
display or continue to press the Right Arrow
button until you do see it.
3 Press SET once and observe the presently
active Rotation Mode showing in the
display.
4 If necessary, press the Up or Down Arrow
button one or two times until
"MODE: TIMED" is displayed.
(NOTE: The mode that was active when the
set point routine was entered will remain
active even when accessing other modes
and their set points. The mode that the ISC
is running will change only upon exiting the
set point routine).
5 Press SET once, observe "SEQ CHG______
HRS".
(NOTE: The display will flash twice in-
dicating the TIMED Mode has been
selected if some other mode had previously
been active).
6 Press the Up or Down Arrow buttons to set
the compressor running hours the ISC is to
accumulate before rotating to the next
sequence.
7 Press SET once to lock in the selected
hours and to return to "ROTATION SET

EVENT ROTATION MODE
In the EVENT rotation mode, the ISC rotates from the
currently running sequence to the sequence specified to
be active at the moment an Event matches the present
day and time. An Event is defined as a user set day of
the week and a user set time of that day. There can be
as many as nine Events entered through the Set Point
routine. Each Event can be preset to start a selected
sequence on a selected day of the week at a selected
time of day. That sequence will remain active until
another Event occurs.
An example of an Event Set Point is shown in the ISC
Set Up Log (Figure 6.7). Using the following rules as
guidelines, decide what Events are needed and write
them in the ISC Set Up Log (Figure 6.7) Then perform
the steps that follow these rules to access the Set Points
and to enter the Events.
EVENT SET UP RULES:
1. Events are numbered 1 through 9, and any number of
them can be used.
2. Each event is enabled by specifying its Sequence,
Day of the Week and Time of Day, or it is disabled by
specifying it as "UNUSED" in place of selecting a
Sequence.
3. Any of the sequences, A through H, can be assigned
to any number of Events. However, a sequence must first
be programmed through the SEQUENCE SET UP Set
Points before it can be assigned to an Event (See
Section 4.2.3 for Sequence Set Up).
4. Any Day of the Week designator can be assigned to
any number of Events. Day of the Week can be any one
of the following choices:
MON Monday
TUE Tuesday
WED Wednesday
THU Thursday
FRI Friday
SAT Saturday
SUN Sunday
DLY Daily - every day of the week
WD Week Day - every day Monday thru Friday
WE Week End - both Saturday and Sunday
5. Any Time of Day can be assigned to any number of
Events. Each Time of Day can be on any hour or quarter
of an hour. Time is entered using the 24-hour clock
method. For example, four-thirty in the afternoon would
be entered as 16:30.
