b
e ue extraction system is mounted correctly.
No
Clean/restore the correct functionality of the ue extraction system.
Check maximum lengths and any obstructions.
Yes
e silicone pipe used for the fan - ues transducer connection is
integral/clean.
No
Restore/replace the silicon pipe.
Yes
Replace the fan. If the anomaly should persist, replace the ues transducer or the circuit board.
ERROR 04
Contacts resistance block
04
e 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
e wiring between the ow probe and the board (X19 connector
terminals 8-9) is OK.
No
Restore the electrical connection/replace the wiring.
Yes
Replace the NTC ow probe. If the anomaly should persist, replace the ue transducer or the circuit board.
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 heating plant and check the correct pre-load of the expansion
vessel .
Yes
e 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 ow meter anomaly
is error occurs when the ue transducer detects a signal that is too high with
the fan at a standstill.
11
e fan is at a standstill.
No
Check the ue extraction system and the correct draught of the ue.
N.B.: the problem could be caused by excessive ue draught or the presence
of other extractors in the ues pipe.
Yes
Replace the ue transducer. If the anomaly should persist, replace the circuit board.
ERROR 12
Storage tank probe anomaly
e boiler prevents functioning in domestichot water mode but it can function
in heating mode.
12
e 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 ow meter out of range
13
Once the boiler has been reset, the anomaly occurs again under the form of Error 15 (see error15 section).
