setpoint. This setpoint helps avoid
Discharge Temperature alarm or shutdown.
High Discharge Temperature Alarm - If the
Discharge Temperature is greater than or equal to
this setpoint, for the alarm time delay, an alarm
occurs.
High Discharge Temperature Shutdown - If the
Discharge Temperature is greater than or equal to
this setpoint, for the shutdown time delay, the
compressor will shut down.
High Discharge Temperature Alarm Delay - The
minimum time in seconds that the Discharge
Temperature is greater than or equal to the high
Discharge Temperature
notification of the alarm.
High Discharge Temperature Shutdown Delay -
The minimum time in seconds that the Discharge
Temperature is greater than or equal to the high
Discharge Temperature
compressor will shut down.
Starting Differential Pressure below - If the
Differential Pressure (the result from subtracting
Suction Pressure from Discharge Pressure) is
greater than or equal to this setpoint, when the
compressor is starting, a start inhibit will be applied.
This can prevent excessive torque on the motor at
startup.
If Dual Discharge Control has been enabled in Factory
Setup, the following Discharge Pressure setpoints will be
necessary for High Discharge Pressure Mode 2 in addition
to High Discharge Pressure Mode 1:
The following Suction Pressure setpoints are on this
control setpoint screen:

Pressure is greater than or equal to this setpoint, the

High Discharge Pressure Stop Load - If the
Discharge Pressure is greater than or equal to this
setpoint, the compressor will be prevented from
further loading until the Discharge Pressure is less
than this setpoint. This setpoint helps avoid forced
unloading.
High Discharge Pressure Force Unload - if the
Discharge Pressure is greater than or equal to this
setpoint, the compressor will be forced to unload until
the Discharge Pressure is less than this setpoint.
This setpoint helps avoid the high Discharge Pressure
alarm or shutdown.
High Discharge Pressure Alarm - If the Discharge
Pressure is greater than or equal to this setpoint, for
the alarm time delay, an alarm occurs.
High Discharge Pressure Shutdown - If the
Discharge Pressure is greater than or equal to this
setpoint, for the shutdown time delay, the compressor
will be shut down.
High Discharge Pressure Alarm Delay - The
minimum time in seconds that the Discharge
Pressure is greater than or equal to the high
Discharge Pressure alarm setpoint before notification
of the alarm.
High Discharge Pressure Shutdown Delay - The
minimum time in seconds that the Discharge Pressure
is greater than or equal to the high Discharge
Pressure shutdown setpoint before the compressor
will shut down.
If Dual Discharge Control has been enabled in Factory
Setup, Enabled will be shown at the control setpoints that
are currently active. The Enabled mode will follow the
current active Capacity Control mode.

until the Suction Pressure is less than this setpoint.
This setpoint helps avoid forced unloading.
