Operation instructions controller
Drying run
The control unit is equipped with a delayed shut-off control for drying the humidifier. This function allows an
enforced shut-off delay of the ventilation system. During operation and after the pump has been switched off, the
floating output is switched on for the set time. Adjustment range: 15 - 120 min. or off.
Step switch
For large humidifiers that use a lot of water, it may be useful to switch the nozzle assemblies in groups. In
transitional periods when less humidification is required, this can be achieved with fewer nozzles and higher
pressure. Depending on the frequency, the nozzle assemblies can be switched on in succession via high pressure
solenoid valves.

Up to 2 levels can be switched,
and for normal rinsing 3 steps can be switched.
If the second set of parameters is needed for a special configuration, the control range extensions (2nd and 3rd
levels) can be determined separately for parameter set P0.
Reset service notice
After the first 200 hours of operation, and then after every 2500 hours of operation, the display will blink red at
intervals and the maintenance notice will be activated. This is to draw attention to a necessary oil change in the
high pressure pump. The humidifier is still operable
This menu item is only available, if the “Service” message appears during operation and the recom-
mended oil change intervals have been exceeded. Once the oil change has been carried out, the mes-
sage can be reset by pressing the left selection key (
) and confirming with the Enter key ( ),
thus initiating a new interval cycle. Proof that the oil change has been carried out must be provided.
Attention! Resetting the service message without an oil change will damage the pump and void the warranty.
