BLOCKAGE AND ERROR CODES
LIST OF ERROR CODES + SOLUTIONS IN ERROR MODE
If a fault occurs during operation, the system locks out and the display starts to ash. The rst character is an “E” or “b” and the following two indicate the code
of this fault, as indicated in the table below.
To unlock the system:
• Press "RESET" on the MCBA interface.
• If the fault repeats, check the error codes below to solve the problem.
Codes
Fault description Fault solutions
E 00
Abnormal flame signal detected
1. Check the wiring (short circuit in the 24 V wiring)
2. Check the electrode
3. Replace the MCBA (water damage)
E 02
No flame presence after five start-up attempts
1. Check the ignition wiring
2. Check the electrode and its position
3. Check the burner gas level
E 03
Gas valve or triac error Replace the rectifier or the gas valve
E 04
Durable locking Press “RESET”
E 05
No flame detection or poor feed current quality
1. Check the electrode gap
2. Check resistance k of the electrode cable
3. Stabilisation of the current
E 06
Detection of an Input error Check the Input and press “RESET”
E 07
Gas valve relay error If the problem persists after two “RESET” attempts, replace the MCBA
E 08
The air pressure switch did not close Check the air pressure switch
E 1 1
EPROM error If the problem persists after two “RESET” attempts, replace the MCBA
E 12
Max input thermostat open or 24 V fuse has blown
1. Check the limit thermostat
2. Check the 24 Volt fuse of the MCBA
3. Link 12-13 missing
E 13
Internal error If the problem persists after two “RESET” ATTEMPTS, replace the MCBA
