11.2.2 Fault switch-off
A fault switch-off is a safety-switch off in the case of flame failure during
operation. After every safety switch-off a new ignition attempt is carried out
as per program. If this does not result in flame formation a fault switch-off
occurs.
In case of fault switch-off, the reset button on the control panel should be
pressed.
In case of operation disturbances (bell symbol in the display), the digit in
the display on the operating panel indicates the cause of the disturbance
(see fault code table).
