Scanning fault messages
If any faults have occurred in your heating system, the
symbol " " flashes on the display and "Fault" is
shown.
The heating contractor uses fault messages to quickly
pinpoint the cause of your boiler's fault. This can
reduce the time required to resolve the fault and there-
fore also your costs.
Make a note of the fault message displayed so you
can advise your heating contractor accordingly. This
makes preparations easier and may save extra travel
expenses.

■ Rectify the fault immediately or have a heating
