Calling up fault messages
Displaying a fault message
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. Make a note of
the fault message displayed, so you can notify your
heating contractor accordingly.
Calling up a fault message
Danger
Unresolved faults in the heating system repre-
sent a risk
If a fault occurs, shut the system down and
■
make it safe.
■
Contact your heating contractor immediately.
■
Rectify the fault immediately or have a heating
contractor rectify it if necessary.
When rectifying the fault, no-one else should
■
be present in the danger zone around the
heating system.
1. You can call up the cause of the fault with
Fault
Outside temp sensor
Fault O2 probe
Acknowledge with

2. Pressing ? calls up information on the heating sys-
tem characteristics.
Also provided are tips on which measures you can
take yourself before notifying your heating contrac-
tor.
Calling up an acknowledged fault message
Press the following keys:
1.
Repeatedly, until the standard menu is dis-

OK
This can reduce the time required to resolve the fault
and save costs.
Note
Operating noise or vibrations can occur due to thermo-
acoustic effects with optimum combustion, but do not
impair the combustion process.
3. Make a note of the cause of the fault and the fault
code shown next to it on the right. In this example:
"Outside sensor 34" and "Fault O2 probe 91".
This enables the heating contractor to be better pre-
pared for the service call and may save additional
travelling costs.
4. If you want to acknowledge the fault message, fol-
low the instructions in the menu.
The fault message is adopted into the menu.

Note
■
If you have connected signalling equipment to
indicate fault messages (e.g. a buzzer), this sig-
nalling equipment is deactivated when the fault
message is acknowledged.
If the fault cannot be rectified until a later date, the
■
fault message is displayed again the next day and
the alarm is switched on again.
■
If a warning message has been acknowledged for
necessary maintenance, the warning message
reappears weekly.
Warning messages can only be reset by the
heating contractor. See "Confirming mainte-
nance" in the installation and service
instructions.
