Description
Condenser water flow status.
Indicates if all available chiller capacity is being used.
Indicates if the chiller is asking an outside system to
provide more heat rejection from the condenser water
loop.
Indicates if compressor 1A is running.
Indicates if compressor 1B is running.
Indicates if compressor 2A is running.
Indicates if compressor 2B is running.
Indicates a request from the chiller to turn on the
evaporator water pump.
Indicates a request from the chiller to turn on the
condenser water pump.
Indicates if the chiller is in a state where noise is being
reduced.
Indicates if water is flowing through the evaporator.
Indicates if an alarm is active.
Indicates if a shutdown alarm is active.
Indicates last diagnostic for the chiller.
