Refrigerant High Pressure

When the wall-mount unit receives a signal from the
compressor control module (CCM) indicating a high
pressure event, the wall-mount unit will generate an
alarm. Upon receiving the alarm, the wall-mount unit
will remove the "Y" call from the CCM, resetting the
status of the CCM. The alarm will stay present on the
wall-mount unit until manually cleared. This operation
has no configurable parameters.

Economizer Damper

When the controller commands the economizer damper
actuator to a position other than 0% and the damper
switch indicates the damper is not open, after a delay
of 20 seconds (Open Del on display) the controller
will generate a damper failed to open alarm. When the
controller commands the economizer damper actuator
to the 0% position and the damper switch indicates
the damper is not closed, after a delay of 300 seconds
(Close Del on display) the controller will generate a
damper failed to close alarm.
