Error codes
ERROR 01
The ignition transformer discharges.
01
The wiring between the ignition electrode and P.C.B. is OK.
a
Check the correct position and correct distance of the ignition electrode and replace it if necessary.
There are 230 V DC on clamps 1-2 of the X1 connector
N.B: measure the voltage within the safety time (8-10 s).
The connectors and relative wiring between gas valve and P.C.B.
are OK.
01
The main coils of the gas valve are OK.
b
The position and the distance of the ignition electrode with respect
to the burner is OK.
Replace the gas valve.
N.B.: before replacing the valve make sure that there is enough gas inlet dynamic pressure and that the gas valve is correctly calibrated.
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 the safety thermostat and P.C.B. is OK.
02
a
Check/replace the safety thermostat. If the anomaly persists, replace the P.C.B.
The safety thermostat functions regularly (intervention temperature
higher than 100°C).
The boiler pump functions correctly.
N.B.: make sure that the pump functions at maximum speed.
02
b
Any CH system zone valve or cut-off cocks are open.
The NTC flow probe is OK (10 kΩ at 25°C).
Check/clean/replace the main heat exchanger.

No See section B
Restore circulation in the CH system by acting on the closed devices
and also check:
- the correct positioning/functioning of the boiler by-pass;
No
- the opening times of any zone valves (when necessary, it is possible to
delay ignition of the burner by acting on the boiler "P8" parameter);
- the correct functioning of any thermostatic valves.
No Replace NTC probe.
