Automatic ventilation
With standard configuration ex factory, when the controller
stops, the connected apparatus is ventilated immediately and
the valve remains open even after the apparatus has been
turned off. As a result, accidental excess pressure situations
are avoided.
However, you can also configure the controller so that hen
the system stops the apparatus is not ventilated. In this case,
you must puss on the Stop key again to ventilate the apparatus.
Attention: Excess pressure situations can arise when the se-
cond operating mode is used. Thus, always remove the
evaporating flask immediately and drain receiving flask!
Configuration possibility: ventilation ON/OFF
