Error codes.

ERROR 01
The ignition transformer carries out the discharge.
01
a
The wiring between ignition electrodes and circuit board is OK.
230 VAC are present on clamps 1-2 of connector X7.
The connector and relative wiring between the gas valve and the
circuit board are OK.
01
b
The gas valve main coils are OK.
Replace the gas valve.
N.B.: before replacing the valve always check that there is sufficient dynamic pressure in gas input and that the adjustment screws of the minimum heat
output and maximum heat ouput are correctly adjusted.
The electrode detects a direct current of 6-8 μA during the burner
01 ignition phase.
c
Replace the P.C.B.
ERROR 02
The wiring between safety thermostat and circuit board is OK.
02
a
Check/replace the safety thermostat. If the anomaly should persist replace the circuit board.
The circulation pump operates correctly.
N.B.: make sure that the pump operates at maximum speed
Any heating system zone valves or intercepting valves are open.
02
b
The NTC flow probe is OK (10 kΩ at 25°C).
Check/clean/replace the main heat exchanger.
ERROR 03
At least 140 VAC are present on clamps 1-2 of connector X16 on
the circuit board.
N.B.: in order to have a reliable measurement the signal must be
read for at least one minute.
To be OK the voltage can be measured for only a few seconds.
03
a
At least 140 VAC are present on the fan clamps.
N.B.: in order to have a reliable measurement the signal must be
read for at least one minute.
To be OK the voltage can be measured for only a few seconds.
Replace the fan.

Ignition block
No Replace the circuit board.
Restore/replace ignition electrodes and relative cables.
No
No Replace the circuit board.
No Restore the electric connection/replace the wiring.
No Where possible, replace the gas valve main coils.
No Replace detection electrodes and/or relative wiring.
Over-temperature safety thermostat block
No Restore the electric connection/replace the wiring.
No See section B
Restore circulation in the heating system by acting on the closed devices
and also check:
- the correct positioning/functioning of the boiler by-pass;
No
- opening times of zone valves (on requirement it is possible to delay
ignition of the burner by acting on the "P68" parameter of the boiler);
- the correct functioning of the thermostatic valves.
No Replace the NTC probe.
Fan anomaly
No Replace the circuit board.
No Restore the electric connection/replace the wiring.
