Parameter Range Function
Alarm – Passive
– Active
Alarm state. Go to settings page for digital alarms. Set all
control-related settings such as alarm delay (default 3600
s).
Min limit 0...99.0 [%rH] oder [g/kg] An alarm is triggered below this humidity.
Maximum deviation 0...99.0 [%rH] oder [g/kg] Maximum allowable deviation between setpoint and ac-
tual value.
Start up delay 0…36000 [s] The function is enabled after this period after a start.
Monitoring is switched off when the humidity sensor fails.
5.11.4 Supply maximum controller
Main Index > Configuration > Configuration 1 > Supply hum sensor = Yes
Main Index > Configuration > Configuration 2 > Hum control mode = Room
Limit supply air humidity for room control only to prevent discharge humidity that is
too high.
Main Index > Unit > Humidity control > Max controller sply
Parameter Range Function
Max controller
sply
0...100 [%rH] oder [g/kg] Actual value for the maximum limit controller. Go to controller
settings page. This is where you enter all control-related set-
tings.
Max setpoint 0.0...100 [%rH] oder [g/kg] Highest allowable supply air humidity for a room humidity
control. Limited control of the humidity controller occurs for
