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 PRO-
GRAM.
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. After pressing
the COOLING SETPOINTS key, the Cooling Mode (Dis-
charge Air Temperature or Suction Pressure Control) will
be displayed for a few seconds, and then the setpoint
entry screen will be displayed.

SETPOINTS KEYS
Following are the four possible messages that can be
displayed after pressing the COOLING SETPOINT key,
indicating the cooling mode:
A I R
This message indicates that the cooling setpoint is un-
der LOCAL control. That is, the cooling setpoint is con-
trolling to the locally programmed setpoint. The mes-
sage also indicates that the control point is based on
Discharge Air temperature leaving the evaporator.
P R E S S U R E
This message indicates that the cooling setpoint is un-
der LOCAL control (the cooling setpoint is controlling to
the locally programmed cooling setpoint). However, un-
like the previous message, it is now indicating that the
control point is based on Suction Pressure.
A I R
This message indicates that the cooling setpoint is un-
der REMOTE control. When under remote control, the
cooling setpoint will be determined by a remote device
such as an ISN control. The message also indicates
that the control point is based on Discharge Air Tem-
perature leaving the evaporator.
