b
The flue extraction system is mounted correctly.
No
Clean/restore the correct functionality of the flue extraction system.
Check maximum lengths and any obstructions.
Yes
The silicone pipe used for the fan - flues transducer connection is
integral/clean.
No
Restore/replace the silicon pipe.
Yes
Replace the fan. If the anomaly should persist, replace the flues transducer or the circuit board.
ERROR 04
Contacts resistance block
04
The over-heating temperature safety thermostat operates normal-
ly.
No
Check the wiring, the cleanliness of the electric connection, the continuity
of the thermostat contact and replace it if necessary.
Yes
Replace the circuit board.
ERROR 05
Flow probe anomaly
05
The wiring between the flow probe and the board (X19 connector
terminals 8-9) is OK.
No
Restore the electrical connection/replace the wiring.
Yes
Replace the NTC flow probe. If the anomaly should persist, replace the flue transducer or the circuit board.
ERROR 10
Insufficient system pressure
10
The boiler manometer displays a pressure exceeding 0.8 bar.
No
Restore the correct pressure by acting on the system filling valve.
N.B.: in this case it is always advisable to ensure that there are no leaks
in the heating plant and check the correct pre-load of the expansion
vessel .
Yes
The wiring between the ab. press. switch and the board is OK
No
Restore the electrical connection/replace the wiring
Yes
Check/replace the system pressure switch. If the anomaly should persist, replace the circuit board.
ERROR 11
Flue flow meter anomaly
This error occurs when the flue transducer detects a signal that is too high with
the fan at a standstill.
11
The fan is at a standstill.
No
Check the flue extraction system and the correct draught of the flue.
N.B.: the problem could be caused by excessive flue draught or the presence
of other extractors in the flues pipe.
Yes
Replace the flue transducer. If the anomaly should persist, replace the circuit board.
ERROR 12
Storage tank probe anomaly
The boiler prevents functioning in domestichot water mode but it can function
in heating mode.
12
The wiring between the storage tank probe and the board (connector
X9 terminals 4-5) is OK.
No
Restore the electrical connection/replace the wiring.
Yes
Replace the storage tank NTC probe. If the anomaly should persist, replace the circuit board.
ERROR 13
Flue flow meter out of range
13
Once the boiler has been reset, the anomaly occurs again under the form of Error 15 (see error15 section).
