Error codes.

ERROR 01
The cables between igniter and electrodes corresponds.
01
a
The igniter makes the spark.
At least 14 V DC is present on clamps 2-3 of the connector X19.
N.B: measure the voltage within the safety time (8-10 s)
01
The wiring between the gas valve and P.C.B. is OK.
b
Replace the gas valve.
N.B.: before replacing the valve make sure that there is enough gas inlet dynamic pressure and that the minimum and maximum output adjustment
are correctly made.
The electrode detects a direct current of 2-4 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 pump functions correctly.
02
Any CH system zone valve or cut-off cocks are open.
b
The NTC flow probe is OK (10 kΩ at 25°C).
Check/clean/replace the main heat exchanger (condensation module).
N.B.: it is recommended to check the correct pressure of the inlet gas and check any obstructions of the gas piping upstream from the boiler. Error 02 intervenes
also if the board detects a loss of the flame signal 6 times in 8.5 minutes.

Restore the electric connection/replace the wiring.
No
Replace the igniter. If the anomaly persists, replace the P.C.B.
No
Replace the P.C.B.
No
Restore the electric connection/replace the wiring.
No
Replace the detection electrode and/or relative wiring.
Check correct position and distance between electrode and burner.
No
Check that siphon and the condensate exhaust duct are not blocked.
Over-heating safety thermostat block
Restore the electric connection/replace the wiring.
No
Replace the over-heating safety thermostat.
No
See section B
No
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 valve (on requirement it is possible to delay
ignition of the burner by acting on the boiler TIMER RT parameter);
- the correct functioning of any thermostatic valves.
Replace NTC probe.
No
