Maximum frequency
With the switching function, you can determine two different maximum frequencies in two sets of parameters.
Parameter P1 represents the normal setting. On special models, the parameter set P0 may be activated without
potential by closing control terminals 5 and 6.
The maximum frequency is factory set. The humidifier is designed for a specific humidification capacity. To
achieve this value, the complete humidification system is synchronised. This setting value is calculated at the
factory and preset and checked during a trial run. Frequency range: 50-87 Hz. Changes can cause damage to
the humidifier.

Pressing the Enter key ( ) in the setting values of “Maximum frequency” will take you to the menu item Fre-
quency limit. If excessive humidity occurs or the water consumption is too high, the frequency can be adjusted
here. It is important to note that the maximum frequency remains unchanged.
Autostart function
The Start and Stop button under the display screen has priority. The “Autostart on” function puts the control unit in
Run mode, when menu navigation is completed and after a control unit reset, i.e. if approval is given and a control
signal is present, the control unit starts the humidifier up again. If “Autostart off” is programmed, the control unit
must be activated via the Start button (
Start
). This setting is useful for maintenance or during longer downtimes.
Power-up time
The power-up time is factory set. This is the time required to reach the designed maximum speed. This is to
ensure that the components of the drive system are not put under unnecessary strain.
With frequent use of the control range extension (2nd level), this time will be preset between 20 and 30 seconds
- but it may vary.
