ERROR 03
Flue safety thermostat anomaly
03
a
e wiring between the ue safety thermostat and P.C.B. is OK.
No
Restore the electric connection/replace the wiring.
Yes
Check/replace the ue safety thermostat. If the anomaly persists, replace the P.C.B.
03
b
Flue evacuation takes place correctly.
No
Check:
- the correct ue draught using the relative tools (micro-manometer,
chromate mirror);
- the suitability of the ue exhaust pipes (measurements, pathways,
position on the roof, etc...).
Both checks must be performed with respect to local regulations.
Yes
Replace the ue safety thermostat. If the anomaly persists, replace the P.C.B.
ERROR 04
Generic boiler P.C.B. anomaly
04
e gas valve is operating correctly.
No
Check the wiring of the electrical connection and make sure it is clean.
Yes
Replace the P.C.B. If the error continues check the quality of the power supply to exclude any external interference.
ERROR 05
Flow probe anomaly
05
e wiring between the ow probe and the board (connector X4
terminals 6-7) is OK.
No
Restore the electric connection/replace the wiring.
Yes
Replace the NTC ow probe. If the anomaly persists, replace the P.C.B.
ERROR 06
Domestic hot water probe anomaly
06
e wiring between the DHW probe and the board (connector X2
terminals 4-5) is OK.
No
Restore the electric connection/replace the wiring.
Yes
Replace DHW NTC probe. If the anomaly persists, replace the P.C.B.
ERROR 10
Insucient system pressure
10
e boiler manometer displays a pressure exceeding 0.8 bar.
No
Restore the correct pressure by acting on the system lling valve.
N.B.: in this case it is always advisable to ensure that there are no leaks
in the central heating plant and check the correct factory-set value of the
expansion vessel.
Yes
e wiring between the absolute pressure switch and the board is OK.
No
Restore the electric connection/replace the wiring.
Yes
Check/replace the system pressure switch. If the anomaly persists, replace the P.C.B.
ERROR 12
Storage tank probe anomaly
(in case of connection to an external storage tank, X versions )
e boiler prevents functioning in DHW mode but can function in CH mode.
12
e wiring between the storage tank probe and the board (connector
X2 terminals 6-7) is OK.
No
Restore the electric connection/replace the wiring.
Yes
Replace the storage tank NTC probe. If the anomaly persists, replace the P.C.B.
