Fan Issue - Event Control
Enable/disable the activation of the [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.
Fan Issue - Event Type The event type for the [Fan Issue] event.
Fan Issue One or more fans are not operating within their operational parameters.
Fan Speed Control
Temperature
Temperature value being used for fan speed control. This value is compared against the
fan speed temperature set point to determine the fan speed.
Fan Speed Maximum Set Point
Maximum fan speed. This value may only be modified if iCOM is enabled to allow fan
speed changes by the BMS.
Fan Speed Minimum Set Point Minimum fan speed.
Fan Speed Temperature Set
Point
If fan is in decoupled mode and not under manual control, the fan speed will vary
depending on the delta between the selected fan control sensor temperature and this set
point.
Fan Speed Fan speed expressed as a percentage of the maximum rated speed.
Fan State Fan operational state.
Fixed Compressor State Fixed compressor operational state.
Fluid Flow Rate Flow rate of fluid used for cooling.
Fluid Flow Sensor Issue The fluid flow sensor is disconnected or the signal is out of range.
Fluid Input Temperature Temperature of the fluid entering the cooling coil.
Fluid Output Temperature Temperature of the fluid exiting the cooling coil.
Fluid Temperature Sensor
Issue
The fluid temperature sensor is disconnected or the signal is out of range.
Free Cooling Fluid
Temperature
Free cooling fluid temperature.
Free Cooling Internal Control
Mode
Free cooling internal control mode
Free Cooling Internal
Temperature Delta
Minimum temperature delta required between supply fluid and internal ambient air
temperatures in order to enable free cooling.
Free Cooling State Free cooling operational state.
Free Cooling Status Free cooling status.
Free Cooling Temp Sensor
Issue
The free cooling fluid temperature sensor is disconnected or the signal is out of range.
Free Cooling Valve Hours
Exceeded
[Free Cooling Valve Hours] has exceeded [Free Cooling Valve Hours Threshold].
Free Cooling Valve Hours
Threshold
Threshold value used in the [Free Cooling Valve Hours Exceeded] event.
Free Cooling Valve Hours
Operating hours for free cooling valve since last reset of this value. If operating hours
exceeds 32,000, this client will continue to display 32,000, but the iCOM display will show
the actual value.
Free Cooling Valve Open
Position
Free cooling valve open position.
Heating Fan Speed Min Set
Point
Minimum fan speed when system heating is active.
High Power Shutdown - Event
Control
Enable/disable the activation of the [High Power 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.
High Power Shutdown - Event
Type
The event type for the [High Power Shutdown] event.
