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.
The following are instructions for programming the
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. After
pressing the COOLING SETPOINTS key, the Cooling
Mode (Discharge Air Temperature or Suction Pressure
Control) will be displayed for a few seconds, and then
the setpoint entry screen will be displayed.
Unit must first be checked for “Unit Type
- Condensing Unit” under the OPTION
key to allow programming of appropriate
setpoints. This is accomplished by the
jumbeforebetween J11-7 and J11-12 on
the I/O Board.
The following are the four possible messages that can
be displayed after pressing the COOLING SETPOINT
key, indicating the cooling mode:
L O C A L D I S C H A R G E
A I R T E M P C O N T R O L
This message indicates that the cooling setpoint is un-
der LOCAL control. That is, the cooling setpoint is
controlling to the
locally
programmed setpoint. The
message also indicates that the control point is based
on Discharge Air temperature leaving the evaporator
coil.
L O C A L S U C T I O N
P R E S S U R E C O N T R O L
This message indicates that the cooling setpoint is un-
der LOCAL control (the cooling setpoint is controlling
to the
locally
programmed cooling setpoint). However,
unlike the previous message, it is now indicating that
the control point is based on Suction Pressure.
R E M O T E D I S C H A R G E
A I R T E M P C O N T R O L
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 Tempera-
ture leaving the evaporator.
