4 .1 Scanning the parameters

During operation, the 7-segment display shows the pro-
gram status, see page 39 (Program status and fault
messages).
The flame signal and all following parameters of the
BCU can be scanned one after the other by repeatedly
pressing the Reset/Information button (for 2 seconds).
In the event of a fault, the BCU halts the program run,
the display blinks and it then displays the cause of the
fault in coded form.
