If any faults have occurred in your heat-

ing system, the symbol flashes on the

display and the fault code is shown. The

red fault indicator also flashes (see

page 10).

Example:

Fault code shown: "50"

1 5 0

1. Notify your heating contractor of the

fault code. This enables the heating

contractor to be better prepared for

the service call and may save addi-

tional travelling costs.

2. Acknowledge the fault message with

OK. The symbol no longer

flashes.

Note

■ If you have connected up signalling

equipment (e.g. a buzzer) for fault

messages, this is deactivated

when the fault message is

acknowledged.

■ If the fault can only be fixed at a

later point in time, the fault mes-

sage will reappear the following

day.

Calling up an acknowledged fault

message

Press OK for approx. 4 s.
