ERROR 01
Ignition block
01
a
The ignition transformer carries out the discharge. No Replace the circuit board.
Yes
The wiring between ignition electrodes and circuit board is OK. No Restore/replace ignition electrodes and relative cables.
01
b
230 VAC are present on clamps 1-2 of connector X7. No Replace the circuit board.
Yes
The connector and relative wiring between the gas valve and the
circuit board are OK.
No Restore the electric connection/replace the wiring.
Yes
The gas valve main coils are OK. No Where possible, replace the gas valve main coils.
Yes
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.
01
c
The electrode detects a direct current of 6-8 μA during the burner
ignition phase.
No Replace detection electrodes and/or relative wiring.
Yes
Replace the P.C.B.
ERROR 02
Over-temperature safety thermostat block
02
a
The wiring between safety thermostat and circuit board is OK. No Restore the electric connection/replace the wiring.
Yes
Check/replace the safety thermostat. If the anomaly should persist replace the circuit board.
02
b
The circulation pump operates correctly.
N.B.: make sure that the pump operates at maximum speed
No See section B
Yes
Any heating system zone valves or intercepting valves are open. No
Restore circulation in the heating system by acting on the closed devices
and also check:
- the correct positioning/functioning of the boiler by-pass;
- 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.
Yes
The NTC flow probe is OK (10 kΩ at 25°C). No Replace the NTC probe.
Yes
Check/clean/replace the main heat exchanger.
ERROR 03
Fan anomaly
03
a
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.
No Replace the circuit board.
Yes
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.
No Restore the electric connection/replace the wiring.
Yes
Replace the fan.
