under the SETPOINTS section.
The three keys involved are labeled COOLING
SETPOINTS, SCHEDULE/ADVANCE DAY, and

respective 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 cooling

temperature SETPOINT at 45.0°F (notice the cursor po-
sitioned under the number 0). Pressing either the ↑ (UP)
or ↓ (DOWN) arrow will change the setpoint in .5°F
increments. After using the ↑ (UP) or ↓ (DOWN) arrow
keys 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.
Entry of the setpoint will be indicated by the cursor mov-
ing 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

for RETURN LIQUID control, the message below
would be displayed in place of the previous message.
