defective (cable break, short circuit) or safety temperature limiter STBK has tripped (e.g. low water
V
R
or pump defective)
During calibration, difference from prior value was too high (unclean supply air, electrode replacement,
electrode defective).
Inflow temperature exceeds limiter temperature (overtemperature, no heat dissipation).
Return flow temperature exceeds limiter temperature (overtemperature, no heat dissipation).
2× no flame formation at end of safety time (no gas, valves do not open, no ignition sparks).
2× flame failure at end of safety time (ionisation electrode defective or dirty)
Gas valve negative. A flame is still detected 15 s after the burner shutdown (gas valve jams).
Speed not reached during pre- and post-ventilation (burner blower defective, power supply to blower,
electronics error in blower, cable break).
Blower stationary position not reached (burner blower defective, electronic error in burner blower).
EEPROM error (manufacturer's parameters).
EEPROM error (safety parameters).
Regulation deviation during ionisation process too high (from 2nd error) (burner earthed incorrectly or
faulty supply voltage combustion control, gas flow pressure too low, ionisation electrode bent or oxidised,
ionisation track faulty, safety gas control block defective).
Impermissible gas fitting initialisation within 10 s (from 2nd error) or
blower falls below 80 % of the minimum speed within 10 s (from 2nd error).
(Burner blower defective, incorrect gas type set, missing/wrong gas nozzle, safety gas control block de-
fective, gas flow pressure too low).
Internal electronic error - from 2nd error (switch device on/off).
A value fell below the minimum limit values during calibration (flue gas recirculation, electrodes oxidised,
ionisation track faulty, poor earthing, transition resistances).
Interruption during calibration (no heat dissipation, minimum calibration time not met).
Impermissible internal value (electronic error).
A value exceeded the maximum limit values during calibration (unclean supply air, basic value too high).
EEPROM error (electronic error).
Error found in the flame amplifier evaluation during the idle state check (electronic error, short circuit ion-
isation electrode or cable).
Combustion control internal error.
Return flow temperature exceeds monitor temperature (overtemperature, no heat dissipation).
Inflow temperature exceeds monitor temperature (overtemperature, no heat dissipation).
Undervoltage with 230 V mains voltage or 18 V internal DC voltage (electronic error, switch device on/
off).
Return flow temperature (t
) is higher than inflow temperature (t
R1
Inflow temperature increase too rapid.
Spread (t
- t
) too large.

R1
Interruption during calibration (no heat dissipation, minimum calibration time not met).
Communication interrupted between combustion control and controller PCB control panel (check cable
and plug connections, total reset, replace controller PCB control panel, replace combustion control).
5x reset within 15 min. Another reset is not possible until after a further 15 min.
Error found in the flame amplifier evaluation during the idle state check (electronic error, short circuit ion-
isation electrode or cable).
Combustion control internal error.
