13.1 Recognising the operating condition and clearing
faults
NOTICE
System damage due to frost.
The heating system can freeze up if it has been switched off through a
fault shutdown.
Rectify the fault immediately and restart the heating system.
Where that is not possible, drain the heating and DHW pipework at
the lowest point.
Depending on which control unit is installed or the user interface used,
faults may be displayed differently. The fault history is also called up in
different ways.
For an overview of the operating and fault codes, along with possible
causes and remedial measures, refer to the technical documentation
of the control unit and the user interface (Chapter 14, page 55).
Some faults have to be cleared using the reset button on the burner
control unit ( Chapter 14, page 55).
Observe corresponding technical documentation for the control unit and
user interface.
