The RANGE should be set in accordance with the
following table:
The RANGE is programmed for +/- X.X° F.
The SETPOINT is in the center of the control
range.
For further details of cooling setpoint programming refer
to Capacity Control Section.
Heating Setpoint
Pressing the SETPOINTS key a second time will display
the heating set point message:
H SETP = XXX.X

The above message shows the current hot water
temperature SETPOINT at XXX.X°C. Pressing the UP
arrow or DOWN arrow will change the SETPOINT
in 0.1°F increments. The ENTER/ADV key must be
pressed to enter the SETPOINT into memory and
advance to the RANGE.
The cursor will move under the current RANGE setting.
Pressing the UP arrow or DOWN arrow will change the
setting between 1.5°F to 4.5°F in 0.1°F increments. The
ENTER/ADV key must be pressed to enter the range
into memory.
The RANGE setting takes into account the number of
compressors on the unit and the temperature difference
between leaving (LLT) and return liquid at full load.
The RANGE should be set in accordance with the table
shown above.
The RANGE is programmed for +/- X.X° F
with the SETPOINT in the center of the
control range.

SCHEDULE/ADVANCE DAY Key
The microprocessor features a continuously running
internal clock and calendar which can display actual
time, day, and date. An automatic schedule feature is
provided for starting and stopping the unit on individual
days of the week, eliminating the need for an external
time clock. Also provided is a holiday feature which
allows special start/stop times to be set for designated
holidays.
If the automatic schedule feature is not required, the
microprocessor can be programmed to run the unit on
demand as long as the unit ON/OFF and system switches
are in the ON position. The daily schedule is considered
not programmed when the times in the schedule are all
zeros (00:00 AM).
Programming of the operating and holiday schedules
are described below.
To set the schedule, press the SCHEDULE/ADVANCE
DAY key. The display will show the following message:
SUN START = 00:00AM
STOP = 00:00AM
