External Condenser TVSS Issue
The condenser Transient Voltage Surge Suppressor or Surge
Protection Device has failed, as indicated by an external input
signal.
External Condenser VFD Issue
The condenser fan Variable Frequency Drive is offline, as indicated
by an external input signal.
External Fire Detected Fire detected, as indicated by an external input signal.
Fan Control Mode Fan control mode.
Fan Control Sensor Sensor to be used for fan speed control.
Fan Hours Exceeded - Event Control
Enable/disable the activation of the [Fan Hours Exceeded] 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 Hours Exceeded - Event Type The event type for the [Fan Hours Exceeded] event.
Fan Hours Exceeded
Operating hours for the unit blower fan have exceeded the
threshold.
Fan Hours Threshold Threshold value used in the [Fan Hours Exceeded] event.
Fan Hours
Operating hours for fan 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.
Fan Issue - Event Control
Enable/disable the activation of the [Fan Issue] event. If set to

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 Control Mode Free cooling internal control mode
