Humidifier Issue - Event Control
Enable/disable the activation of the [Humidifier 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.
Humidifier Issue - Event Type The event type for the [Humidifier Issue] event.
Humidifier Issue Humidifier issue detected, causing it to be locked out.
Humidifier Lockout Enable/disable the use of the humidifier.
Humidifier Low Water The 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.
