Data Description
Definitions
Ext Air Sensor A
Temperature
Air temperature as measured by External Air Sensor A.
Ext Air Sensor A Under
Temperature
(Ext Air Sensor A Temperature) has dropped below (Ext Air Under Temp Threshold).
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).
Fan Issue
One or more fans are not operating within their operational parameters.
Hot Gas Solenoid Valve 1
Position
Hot gas solenoid Valve 1 position.
Hot Gas Solenoid Valve
2 Position
Hot gas solenoid Valve 2 position
Hot Gas Valve 1 Open
Position
Hot gas Valve 1 open position.
Hot Gas Valve 2 Open
Position
Hot gas Valve 2 open position.
Maintenance Ramp
The ratio of operations performed to the calculated operations available between maintenance intervals.
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.
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.
Pump Short Cycle
Pumps have short cycled. A short cycle is defined as turning On and Off a number of times over a set time period.
Shutdown - Loss Of
Power
System lost power. This event becomes active when the unit is powered on following an unexpected loss of power.
Supply Refrig Over
Temp Threshold
Threshold value used in the (Supply Refrigerant Over Temp) event.
Supply Refrig Over
Temp Threshold
Threshold value used in the (Supply Refrigerant Over Temp) event.
Supply Refrigerant Over
Temp
Event that is activated when (Supply Refrigerant Temperature) exceeds (Supply Refrig Over Temp Threshold). The event
is deactivated when the temperature drops below the threshold.
Supply Refrigerant
Temp Sensor Issue
The supply refrigeramt temperature sensor is disconnected or the signal is out of range.
