MCBA PARAMETERS FOR THE SPECIALIST

Codes

Description of the fault

Resolution of the fault

Abnormal flame signal

- Check the wiring (short-circuit in the 24V wiring)
- Check the electrode
- Replace the MCBA (water damage)

No flame signal after five attempts at firing the boiler

- Check the ignition cable
- Check the electrode and the position of the electrode
- Check that there is gas at the burner.

Internal error

If the problem persists after two

RESET

attempts,

replace the MCBA.

Persistent lock

Press

RESET

Internal error

If the problem persists after two

RESET

attempts,

replace the MCBA.

EPROM error

If the problem persists after two

RESET

attempts,

replace the MCBA.

Max input, thermostat open or 24V fuse gone.

- Check the wiring
- Check the 24V fuse on the MCBA.
- Missing shunt 12-13

Internal error

If the problem persists after two

RESET

attempts,

replace the MCBA.

T1 > 110°C

- Check the NTC wiring and replace if necessary.
- If NTC1 is OK, please verify that the water flows trough the
boiler.

T2 > 110°C

- Check the NTC wiring and replace if necessary.

T1 gradient too high

- Check that the pump is turning.
- If there is no problem with the pump, drain the system.

No fan signal present

- Check the fan control connection
- Check the fan wiring

If the problem persists after two

RESET

attempts,

replace the MCBA.

The tacho signal of the blower does’nt go to zero.

- Check that the convection flow through the chimney is not
high enough to rotate the blower.

If not, exchange the blower.

NTC1 short-circuit

- Check the connection of the NTC1 sensor
- Check the wiring of the NTC1 sensor

If the problem persists, replace the NTC1 sensor

NTC2 short-circuit

- Check the connection of the NTC2 sensor
- Check the wiring of the NTC2 sensor

If the problem persists, replace the NTC2 sensor

To unlock the system:

• Press RESET on the screen.

• Contact your installer if the fault happens again.

SAFETY STOP+ RESOLUTION OF THE FAULT
[ERROR mode]

If a fault occurs while the appliance is running, the system locks
and the screen starts to flash.
The first character is an

and the next two characters give the

code for this fault, as illustratedin the table below.
