Functions
Function
gate.
– (additional) 2 step direct expansion evaporator aggre-
gate.
– (additional) 3 step direct expansion evaporator aggre-
gate.
– No humidification and dehumidification.
– Humidification only.
– Dehumidification only.
– Humidification and dehumidification.
Function
Type of humidity control.
– No humidity control.
– Room control only.
– Supply air temperature control only.
– Room / supply air temperature cascade control.
Type of humidity control.
– Relative humidity control.
– Absolute humidity control.
– Cascade control with relative room and absolute supply
air humidity control.
Predefined variants for humidity setpoints:
– Humidification and dehumidification setpoint is entered
directly.
– Base setpoint and dead zone is entered.
– Humidification setpoint and dead zone is entered.
– Dehumidification setpoint and dead zone is entered.
Dehumidification is reduced dependent on the heating
output:
– Function not enabled.
– As of 90%, heating valve position reduces dehumidifica-
tion.
Dew point monitoring.
Monitors setpoint/actual value of humidification. An alarm
is triggered for deviations over a certain period:
– No monitoring.
– Monitors room humidity only.
– Monitors supply air humidity only.
– Monitors supply air and room humidity.
– No humidifying pump.
– Humidifying pump without pump kick.
– Humidifying pump with pump kick.
– Pump without alarm or feedback.
– Pump with alarm.
– Pump with feedback.
– Pump with alarm and feedback.
– Humidifier without feedback.
– Humidifier with feedback.
