Range Function
Type of humidity control.
Relative Relative humidity control.
Absolute Absolute humidity control.
CascRelAbs Cascade control with relative room and absolute supply air humidity
control.
Predefined variants for humidity setpoints.
Hum/dehum Humidification and dehumidification setpoint is entered directly.
+/- HalfDz Base setpoint and dead zone is entered:
Humidity setpoint = Base setpoint – half dead zone.
Dehumidification setpoint = Base setpoint – half dead zone.
Hum+Dz Humidification setpoint and dead zone is entered:
Dehumidification setpoint = Humidification setpoint + dead zone.
dehum-Dz Dehumidification setpoint and dead zone is entered:
Humidification setpoint = Dehumidification setpoint – dead zone.
Dehumidification is reduced dependent on the heating output.
No Function not enabled.
Yes As of 90%, heating valve position reduces dehumidification.
No Dew point monitoring. Minimum limitation to supply air temperature
Yes relating to dew point control.
Monitors setpoint/actual value of humidification. An alarm is triggered
for deviations over a certain period.
No No monitoring.
Room/Exh Monitors room humidity only.
Supply Monitors supply air humidity only.
Sply+RmExh Monitors supply air and room humidity.
No No humidifying pump.
Yes Humidifying pump without pump kick. Digital output for the pump.
Yes+Kick Humidifying pump with pump kick. A digital output for pump and acti-
vation of pump kick.
Pump kick: Pump is switched on for a short period after idling for a
longer period. This prevents lock up.
No Pump without alarm or feedback.
Alarm Pump with alarm. Digital input for pump alarm. Logical 1 = alarm, im-
mediately shuts down the pump.
Fdbk Pump with feedback. Digital input for feedback (logical 1 = Pump run-
ning).
Both Pump with alarm and feedback. Two digital inputs for pump alarm and
feedback.
No Humidifier without feedback.
Yes Humidifier with feedback: Digital input for feedback is enabled (logical
1 = Humidifier running).
No No water cooling pump.
Yes Water cooling pump without pump kick. Digital output for the pump.
Yes+Kick Water cooling pump with pump kick. A digital output for pump and ac-
tivation of pump kick.
Pump kick: Pump is switched on for a short period after idling for a
longer period. This prevents lock up.
No Pump without alarm or feedback.
Alarm Pump with alarm. Digital input for pump alarm. Logical 1 = alarm, im-
mediately shuts down the pump.
Fdbk Pump with feedback. Digital input for feedback (logical 1 = Pump run-
ning).
