Resetting using the Reset button
Zone 22
Resetting via the reset button is not possible in zone 22 because the enclosure must be
opened for this purpose.

Resetting without the BusAdapter is not possible because startup of the CFU is prevented.
You can reset the CFU to factory settings.
Select a pin with the following dimensions for the reset (for example a paper clip):
