Automatic operation
In automatic operation the set value for the negative pressure in Pascal is entered with
the buttons „+“ and „-“ (display set value in automatic operation). By comparing the
entered set value with the permanently measured actual value (measured negative
pressure) the speed of the fan is automatically adjusted, i.e. the fan moves automatically
“up” or “down”.
Manual operation:
In manual operation the fan capacity is set with the buttons „+“ and „-“. The performance
in % and the measured negative pressure are shown in the display. In manual operation
the machine does not adjust automatically!
In case of power failure the control saves the date set last, starts after recovery
automatically and re-establishes the saved data.
