This logic group is a solution that briefly activates the affected roller blind for ventilation when windows are opened.

Here is a brief explanation of this logic group:

With this function, attention has been paid to ensuring that the blind is not only opened, but that the original position is returned to when it is "closed again".

In addition, the blind only moves to the ventilation position if it was previously closed.

In practice, an Enocean window contact is used on windows or patio doors.
