Malfunction catch / malfunction handling
If "unlock malfunction catch" is wired malfunctions that occur are saved and can be reset by
activating the "unlock malfunction catch".
If a malfunction occurs for "malfunction locking" = 1 the fan is switched off completely.
A malfunction that occurs SM1 or SM2 or stCEC1 or stCEC2 may influence the control of the outputs
"Fan 1 ON level 1" and "Fan ON level 2" as follows:
1. not ("malfunction blocked" = 0)
2. switches the outputs "request cover", "fan on level 1", "fan on level 2" and "request
control" off immediately and completely.
("malfunction blocked" = 1)
If the malfunction switches off the outputs "Fan ON level 1", and "Fan ON level 2" this can only be
reset by activating the "release malfunction catch".
If "unlock malfunction catch" is not wired malfunctions that occur are not saved, i.e. if the
malfunction disappears the malfunction handling disappears.
