Humidifier Issue Humidifier issue detected, causing it to be locked out.
Humidifier Lockout Enable/disable the use of the humidifier.
Humidifier Low Water Th e water level in the humidifier has dropped below its threshold.
Humidifier Over Current The electrical current to the humidifier has exceeded its upper threshold.
Humidifier State Humidifier operational state.
Humidifier Under Current The electrical current to the humidifier has dropped below its lower threshold.
Humidifier Utilization Present humidifier utilization expressed as a percentage of the maximum rated
capacity.
Humidity Control Sensor Sensor from which humidity measurements will be used for humidification and
dehumidification control.
Humidity Dead Band
Value that is divided evenly to form a range above and below [Humidity Set Point]. If
measured humidity is within this range, no humidification or dehumidification will
occur.
Humidity Proportional Band Value that is divided evenly to form proportional humidity control bands above and
below [Humidity Set Point].
Humidity Proportional Control
Integration Time
Time value used to add an integral term to proportional humidity control. If set to 0,
time will not be a factor in the proportional control algorithm.
Humidity Proportional Control Type Type of algorithm to use for proportional control of output humidity.
Humidity Proportional Control Type Type of algorithm to use for proportional control of output humidity.
Humidity Set Point Desired relative humidity.
Infrared Humidifier Flush Rate A multiple of an internal time constant that determines the flush duration of the infrared
humidifier water pan.
Input Undervoltage One or more of the input phase voltages has dropped below the limit.
Instantaneous Power Total electrical power currently being consumed.
Loss of Air Flow No air flow through the unit due to failure of all fans.
Low Return Humidity - Event
Control
Enable/disable the activation of the [Low Return Humidity] 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.
Low Return Humidity - Event Type The event type for the [Low Return Humidity] event.
Low Return Humidity Threshold Threshold value used in the [Low Return Humidity] event.
Low Return Humidity Return air low humidity event.
Low Static Pressure Low static pressure event.
Main Chilled Water Valve The primary valve in a dual valve chilled water system.
Main Fan Overload - Event Control
Enable/disable the activation of the [Main Fan Overload] 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.
Main Fan Overload - Event Type The event type for the [Main Fan Overload] event.
Main Fan Overload Main fan is shut down due to thermal overload.
Maintenance Completed Maintenance has been completed on the uni t.
Maintenance Due The calculated maintenance date has been reached.
Maintenance Ramp The ratio of operations performed to the calculated operations available between
maintenance intervals.
Maintenance Tracking State Maintenance tracking operational state.
Master Unit Communication Lost -
Event Control
Enable/disable the activation of the [Master Unit Communication Lost] 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.
