10.1.3 Illuminated push button flashes

An irregularity is present. The burner does not go to lockout. Once the fault has
been rectified, the error code ceases.

Error codes without lockout

The following faults must only be rectified by qualified personnel:

Fault codes

Cause

Rectification

Flashing green/red

Flame signal at heat demand

Find and eliminate perturbation

Flame formation caused by leaking
solenoid valve

Replace multifunction assembly

Flashing red/orange with pause Excess voltage

Check voltage supply

Flashing orange/red

Low voltage

Check voltage supply

Internal unit fuse (F7) faulty

Replace fuse [ch. 9.16]

Combustion manager fault

Replace combustion manager

Flashing red

Bridging plug No. 2 is missing

Plug in bridging plug No. 2

Low gas

Check gas connection pressure
Set gas pressure switch [ch. 7.3.1]
Check gas pressure switch

orange, after 2 minutes red

Air pressure switch does not react

Set air pressure switch [ch. 7.3.2]
Check air pressure switch
With ducted air intake air pressure
switch, check air supply

Flashing green

Burner operation with weak flame signal Minimum ionisation current 1.5 μA

Check burner setting

Ionisation electrode soiled

Clean ionisation electrode

Ionisation electrode defective

Replace ionisation electrode

Glimmering red

OCI mode activated (not used)

Press illuminated push button for
more than 5 seconds
Combustion manager changes to op-
erating mode
