On parameterization, ensure that the program se-
quence started matches the application. This param-
eter may be set in this way only if the burner can restart
as intended in all operating phases.
4.1 Scanning the parameters
During operation, the 7-segment display shows the pro-
gram status, see page 27 (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 s).
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.
