Actual Supply Fluid Temp Set Point

The actual set point value being used for the desired fluid temperature at the outlet 

of the unit.

All Pumps Loss of Flow

System is shut down due to loss of flow in all available pumps.

Ambient Air Temperature Sensor Issue

The ambient air temperature sensor is disconnected or the signal is out of range.

Ambient Air Temperature

Ambient air temperature.

Compressor Capacity Control State

Compressor capacity control state. When 'ON', the cooling capacity of the 

compressor has been reduced.

Compressor Capacity Normal

Compressor has returned to normal load capacity.

Compressor Capacity Reduced

Compressor capacity has been reduced.

Compressor Contactor Issue

Compressor contactor is not closing during compressor startup or is not opening 

during compressor shutdown.

Compressor Economizer Utilization

Present compressor economizer utilization expressed as a percentage of the 

maximum.

Compressor Head Pressure

Compressor head pressure.

Compressor High Head Pressure

Compressor is shut down due to high head pressure.

Compressor Hours Exceeded

[Compressor Hours] has exceeded [Compressor Hours Threshold].

Compressor Hours Threshold

Threshold value used in the [Compressor Hours Exceeded] event.

Compressor Hours

Operating hours for compressor since last reset of this value.

Compressor Loss of Differential 

Pressure

Compressor is shut down due to low differential pressure.

Compressor Low Oil Pressure

Compressor low oil pressure.

Compressor Low Suction Pressure

Compressor is shut down due to low suction pressure.

Compressor Not Stopping

Compressor commanded to stop, but continues to run.

Compressor Shut Down - Ambient Air 

Low Temp Limit

When the temperature of ambient air falls below this lower threshold, the 

compressor will be shut off. Correct condensing pressure cannot be achieved 

when temperature is too low.

Compressor State

Compressor operational state.

Compressor Superheat Over 

Threshold

Compressor discharge refrigerant superheat temperature has exceeded an upper 

threshold.

Compressor Thermal Overload

Compressor is shut down due to thermal overload.

Compressor Utilization

Present compressor utilization expressed as a percentage of the maximum rated 

capacity.

Condenser Adiabatic Cooling 

Utilization

Present adiabatic cooling utilization expressed as a percentage of the maximum.

Condenser Fan Issue

Condenser fan is not operating within its operational parameters.

Condenser Fan Speed

Condenser fan speed expressed as a percentage of the maximum rated speed.

Condenser Inlet Water Temperature

For water cooled condensers, the temperature of the water entering the heat 

exchanger, before cooling the refrigerant.

Condenser Max Fan Speed Override

Fan speed exceeding the maximum set point in order to alleviate a high 

temperature or pressure condition.

Condenser Outlet Water Temperature

For water cooled condensers, the temperature of the water exiting the heat 

exchanger, after cooling the refrigerant.
