Schedule Key Operation
The Daily Schedule must be programmed for the unit

SCHEDULE key. The display will provide a message
allowing access to 2 types of schedule information:
SCHEDULE CHOOSE SCHEDULE TYPE
< > UNIT OPERATING SCHEDULE
The schedule types are:
• UNIT OPERATING SCHEDULE (Default
selection)
• SOUND LIMIT SCHEDULE (Only if Sound
Limiting is enabled by the factory when the option
is installed.)
The schedule type (UNIT OPERATING SCHEDULE
or SOUND LIMIT SCHEDULE) may be changed
by pressing the ◄ (LEFT ARROW) or ► (RIGHT
ARROW) keys followed by the (ENTER) key. The
selection must be entered by pressing the  (ENTER)
key before a schedule display will appear.
Unit Operating Schedule
The Unit Operating Schedule is used to enable/disable
the chiller unit on time of day. The chiller can be enabled
and disabled once each day or it can be programmed
to run continuously. Any time the daily or holiday
schedule shuts the chiller down, the running system(s)
will go through a controlled ramped shutdown. If the
UNIT OPERATING SCHEDULE is selected under the
CHOOSE SCHEDULE display, the following message
will appear:
SCHEDULE UNIT OPERATING
SUN START = 00:00 AM STOP = 00:00 AM
The line under the 0 above is the cursor. If the start
time is wrong, it can be changed by keying in the new
time from the numeric keypad. Once the correct values
for the START hour and minute are entered, press the
 (ENTER) key. The cursor will then move to the
AM/PM selection. The meridian (AM/PM) value may
be changed by the ◄ (LEFT ARROW) or ► (RIGHT
ARROW) keys and entered by pressing  (ENTER) key.
Repeat this process for the STOP time. Once a schedule
is entered, the schedule for the next day will appear.
The start and stop time of each day may be programmed
differently.
To view the schedule without making a change, simply
press the SCHEDULE key until the day you wish to
view appears. The ▲ (UP ARROW) key will scroll
backwards to the previous screen.
If at any time the schedule is changed for
Monday, all the other days will change to
the new Monday schedule. This means if
the Monday times are not applicable for the
whole week, then the exceptional days
would need to be reprogrammed to the
desired schedule.
To program the chiller for 24 hour operation, program
the start and stop times of each day of the week for 00:00.
After the SUN (Sunday) schedule appears on the display,
a subsequent press of the SCHEDULE or ▲ (UP
ARROW) key will display the Holiday schedule. This is
a two-part display. The first reads:
SCHEDULE UNIT OPERATING
HOL START = 00:00 AM STOP = 00:00 AM
The holiday times may be set using the same procedure
as described above for the days of the week. Be sure to
press the  (ENTER) key after setting the START and
STOP times to save the change in memory.
Pressing the SCHEDULE key a second time, the display
will show the individual days:
SCHEDULE UNIT OPERATING
S M T W T F S HOLIDAY NOTED BY *
The line below the empty space is the cursor and will
move to the next or previous empty space when the ◄
(LEFT ARROW) or ► (RIGHT ARROW) keys and
pressed. To set a day for the Holiday Schedule, the
cursor must be moved to the space following the day of
the week. The * key is then pressed and an “*” will
appear in the space signifying that day as a holiday.
