Calling up fault messages
If any faults have occurred in your heating system, the
symbol " " flashes in the display and "Fault" is
shown.
The heating contractor uses fault messages to quickly
pinpoint the cause of the fault. This can reduce the
time required to resolve the fault and therefore also
your costs.
You should therefore note down the fault message
before getting in touch with your heating contractor so
you can tell the engineer what it is. This makes prepa-
rations easier and may save extra travel expenses.
Danger
Danger due to unresolved faults in the heating
system.
■
If a fault occurs, shut the system down and
make it safe.

Contact your heating contractor immediately.
Have the fault rectified immediately.
■
When rectifying the fault, no-one else should
■
be present in the danger zone around the
heating system.

This enables the heating contractor to be better pre-
pared for the service call and may save additional
travelling costs.

If you have connected signalling equipment to
indicate fault messages (e.g. a buzzer), this is
deactivated when the fault message is acknowl-
