Error codes.

ERROR 01
The ignition transformer discharges.
01
a
The wiring between the ignition/detection electrode and P.C.B.
is OK.
230 V AC are present on clamps 11-12 of connector X7.
N.B: measure the voltage within the safety time (8-10 s)
The connector and relative wiring between gas valve and P.C.B.
are OK.
01
The main coils of the gas valve are OK.
b
Is the position and distance of the ignition/detection electrode
correct with respect to the burner? (see gas circuit chapter).
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 regulated.
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).Replace the over-heating safety thermostat.
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 bithermal heat exchanger.
ERROR 03
The wiring between the flue safety thermostat and P.C.B. is OK.
03
a
Check/replace the flue safety thermostat. If the anomaly persists, replace the P.C.B.
Flue evacuation takes place correctly.
03
b
Replace the flue safety thermostat. If the anomaly persists, replace the P.C.B.

Over-heating safety thermostat block
No Restore the electric connection/replace the wiring.
No The pump functions correctly.
No See section B
Restore circulation in the CH system by acting on the closed devices
and also check:
- the correct functioning of the boiler by-pass;
No
- the opening times of any zone valves;
- the correct functioning of any thermostatic valves.
No Replace NTC probe.
Flue safety thermostat block
Restore the electric connection/replace the wiring.
No
Check:
- the correct flue draught using the relative tools (micro-manometer,
chromate mirror);
No
- the suitability of the flue exhaust pipes (measurements, pathways,
position on the roof, etc...).
Both checks must be performed with respect to local regulations.
