Checking 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.
Danger
Fault messages indicate faults in the heating
system. If faults are not rectified, they can have
life threatening consequences.
■
Do not acknowledge the fault message sev-
eral times in quick succession.
■
If a fault occurs, shut the system down and
make it safe.
■
Rectify the fault or contact your heating con-
tractor immediately.
■
When rectifying the fault, no-one else should
be present in the danger zone around the
heating system.
