Pump water shortage
5.1
Fault display
Fault messages have priority over all other displays. If a
fault develops in the boiler, the display shows a fault code
instead of the basic display. A plain text display explains the
displayed fault code.
Example for F.75: "Fault Pump water shortage".
If multiple faults occur at the same time, the display shows
the corresponding fault codes for two seconds each in
sequence.
>
If your boiler displays a fault message, contact your
approved competent person.
You can use the "Live monitor" function to call up status
messages about the status of your boiler
(
¬ section 6.2
).
