4 .1 Scanning the parameters

During operation, the 7-segment display shows the pro-
gram status.
The flame signal and all following parameters of the
PFU can be scanned one after the other by repeatedly
pressing the Reset/Information button (for 2 s).
In the event of a fault, the PFU halts the program run,
the display blinks and it then displays the cause of the
fault in coded form.
