Data Description
Condenser refrigerant pressure has exceeded a threshold.
Condenser refrigerant pressure sensor is disconnected or the signal is out
of range.
Condenser refrigerant pressure has dropped below a threshold.
Condenser supply refrigerant temperature has exceeded a threshold.
Condenser supply refrigerant temperature sensor is disconnected or the
signal is out of range.
Condenser supply refrigerant temperature has dropped below a specified
threshold.
The condenser Transient Voltage Surge Suppressor device has failed.
One or more unspecified condenser unit events active. See local unit
display for further details.
The condenser fan Variable Frequency Drive is offline.
Compressor utilization or chilled water valve position, based on unit type.
Temperature control band above [Air Temperature Set Point]. If measured
air temperature is within this band, cooling operations are proportionally
controlled.
Customer Input 1.
Customer input 2.
Customer input 3.
Customer input 4.
Humidity control band above [Humidity Set Point]. If measured humidity is
within this band, dehumidification operations are proportionally controlled.
Operating hours for the dehumidifier have exceeded the threshold.
Present dehumidifier utilization expressed as a percentage of the maximum
rated capacity.
Digital scroll compressor 1 shut off because its head temperature has
exceeded the upper threshold.
Digital scroll compressor 1 temperature sensor is disconnected or the
signal is out of range.
Operating hours for electric reheater have exceeded the threshold.
The compressor is shut down and disabled by an external input signal.
High water is detected in the condenser, as indicated by an external input
signal.
The humidifier is shut down and disabled by an external input signal.
Loss of flow is detected, as indicated by an external input signal.
A temperature has exceeded its threshold, as indicated by an external input
signal.
The reheater is shut down and disabled by an external input signal.
The standby glycol pump is on, as indicated by an external input signal.
Fire detected, as indicated by an external input signal.
Fan control mode. Allowable modes are: (0) Auto - Fan speed is controlled
via the selected fan control sensor, and, (1) Manual - Fan will operate at a
fixed speed.
Sensor from which air temperature measurements will be used for fan
speed control.
Operating hours for the unit blower fan have exceeded the threshold.
Manual fan speed.
Maximum fan speed.
Minimum fan speed.
