Ext Air Sensor B Dew Point Temp Dew point temperature as measured by external air sensor B.
Ext Air Sensor B Humidity Relative humidity as measured by external air sensor B.
Ext Air Sensor B Issue The external air sensor B is disconnected or the signal is out of range.
Ext Air Sensor B Over Temperature [Ext Air Sensor B Temperature] has exceeded [Ext Air Over Temp Threshold].
Ext Air Sensor B Temperature Air temperature as measured by external air sensor B.
Ext Air Sensor B Under Temperature [Ext Air Sensor B Temperature] has dropped below [Ext Air Under Temp Threshold].
Ext Air Under Temp Threshold
Threshold value used in the ([Ext Air Sensor A Under Temperature], [Ext Air Sensor
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.
Ext Remote Shutdown Unit is shut down by a remote signal.
Ext System Condensation Detected -
Event Control
Enable/disable the activation of the [Ext System Condensation Detected] 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 System Condensation Detected -
Event Type
The event type for the [Ext System Condensation Detected] event.
Ext System Condensation Detected External system condensation detected.
Fan Button Control Enable or disable the buttons from controlling the state of the fans.
Fan Economy Mode Mode in which system secondary fans are to be controlled.
Fan Issue One or more fans are not operating within their operational parameters.
Fan On/Off Control Turn system fans on or off.
Fan State Current operational state of a group of fans.
Hot Aisle Over Temp Threshold Upper threshold value used in the [Hot Aisle Temp Out of Range] event.
Hot Aisle Temp Out of Range
The air temperature in the Hot aisle is either above [Hot Aisle Over Temp Threshold]
or below [Hot Aisle Under Temp Threshold].
Hot Aisle Under Temp Threshold Lower threshold value used in the [Hot Aisle Temp Out of Range] event.
Maintenance Completed Maintenance has been completed on the unit.
Maintenance Due The calculated maintenance date has been reached.
Maintenance Ramp
The ratio of operations performed to the calculated operations available between
maintenance intervals.
Master Unit Communication Lost Communication with master unit has been lost.
Minimum Room Temperature Set
Point
Minimum desired room air temperature. If the room air temperature falls below this
set point, the unit will reduce the cooling.
Primary Fan Group State Current operational state of the primary fan group.
Pump 1 Loss of Flow
Loss of flow is detected in pump 1. The loss of flow condition occurs when no
differential pressure is detected across the pump.
Pump 1 State Pump 1 operational state.
Pump 2 Loss of Flow
Loss of flow is detected in pump 2. The loss of flow condition occurs when no
differential pressure is detected across the pump.
Pump 2 State Pump 2 operational state.
