Data Label Data Description
Auto Restart Delay
If power is lost, the control will delay this amount of time after power is restored
before restarting the unit.
Calculated Next Maintenance Month
Calculated month of the next scheduled maintenance. Used in conjunction with
[Calculated Next Maintenance Year].
Calculated Next Maintenance Year
Calculated year of the next scheduled maintenance. Used in conjunction with
[Calculated Next Maintenance Month].
Chilled Water Control Valve Failure
Chilled water valve out of position. Chilled water control valve position does not
match expected value.
Chilled Water Valve Open Position Chilled water valve open position.
Cold Aisle Over Temp Threshold Upper threshold value used in the [Cold Aisle Temp Out of Range] event.
Cold Aisle Temp Out of Range
The air temperature in the cold aisle is either above [Cold Aisle Over Temp
Threshold] or below [Cold Aisle Under Temp Threshold].
Cold Aisle Under Temp Threshold Lower threshold value used in the [Cold Aisle Temp Out of Range] event.
Communication Status Communication status of remote device.
Cooling Capacity Cooling capacity in use, expressed as a percentage of the maximum rated capacity.
Cooling Capacity Cooling capacity in use, expressed in kilowatts.
Customer Input 1 Customer input 1.
Dew Point Temperature Dew point temperature, using the highest reading from all sensors.
Ext Air Over Temp Threshold
Threshold value used in the ([Ext Air Sensor A Over Temperature], [Ext Air Sensor B
Over Temperature]...) events.
Ext Air Sensor A Dew Point Temp Dew point temperature as measured by external air sensor A.
Ext Air Sensor A Humidity Relative humidity as measured by external air sensor A.
Ext Air Sensor A Issue The external air sensor A is disconnected or the signal is out of range.
Ext Air Sensor A Over Temperature [Ext Air Sensor A Temperature] has exceeded [Ext Air Over Temp Threshold].
Ext Air Sensor A Temperature Air temperature as measured by external air sensor A.

B Under Temperature]...) events.
Ext Dew Point Over Temp Threshold Threshold value used in the [Ext Dew Point Over Temperature] event.
Ext Dew Point Over Temperature
At least one dew point temperature reading ([Ext Air Sensor A Dew Point Temp],
[Ext Air Sensor B Dew Point Temp]...) has exceeded [Ext Dew Point Over Temp
Threshold].
Ext Fan Issue - Event Control
Enable/disable the activation of the [Ext Fan Issue] event. If set to “disabled,” the
event will not be annunciated. This implies that the event will not be placed in any
active event list or in any event history list.
Ext Fan Issue - Event Type The event type for the [Ext Fan Issue] event.
Ext Fan Issue One or more fans are not operating within their operational parameters.
Ext Remote Shutdown - Event
Control
Enable/disable the activation of the [Remote Shutdown] event. If set to “disabled,”
the event will not be annunciated. This implies that the event will not be placed in
any active event list or in any event history list.
Ext Remote Shutdown - Event Type The event type for the [Remote Shutdown] event.
