Programming of the cooling setpoints, daily schedule,
and safeties is accomplished by using the keys located
under the SETPOINTS section.
The three keys involved are labeled COOLING
SETPOINTS, SCHEDULE/ADVANCE DAY, and
PROGRAM.
Following are instructions for programming the respec-
tive setpoints. The same instruction should be used to
view the setpoints with the exception that the setpoint
will not be changed.
COOLING SETPOINTS
The Cooling Setpoint and Range can be programmed by
pressing the COOLING SETPOINTS key.

The above message shows the current chilled water
temperature SETPOINT at 45.0°F (notice the cursor
positioned under the number 0). Pressing either the UP
or DOWN arrow will change the setpoint in .5°F incre-
ments. After using the UP and DOWN arrows to adjust
to the desired setpoint, the ENTER/ADV key must be
pressed to enter this number into memory and advance
to the RANGE SETPOINT.
This will be indicated by the cursor moving under the
current RANGE setpoint. The UP and DOWN arrow
keys are used to set the RANGE, in .5 °F increments,
to the desired RANGE setpoint. After adjusting the
setpoint, the ENTER/ADV key must be pressed to enter
the data into memory.
Notice that the RANGE was programmed for
+/
x.x° F.
This indicates the SETPOINT to be in the
center
of the
control range. If the control mode has been programmed
for RETURN LIQUID control, the message below
would be displayed in place of the previous message.
