Shut-down for fan malfunction
The fan operation is constantly monitored and in case of malfunction the burner goes off; the code E40 flashes on the display.
This mode is maintained until the fan recovers normal working parameters.
If the boiler does not start and remains in this mode, contact a Service Centre or a qualified service engineer.

Alarm due to temperature probe malfunction
The following fault codes are shown on the display in the event of burner shut-down due to a temperature probe fault:
- E05 for the CH probe. In this case the boiler ignition is disabled.
- E12 for the water heater probe. In this case, the boiler works in standard mode, "comfort" function excluded.
- E15 for the return probe. In this case the boiler does not work.
- E36 for CH flow probe in one of the installed zones (V and Z versions). In this case boiler ignition is disabled only for the zone affected by the fault.
All other zones operate correctly.
In any case, contact a Service Centre or qualified personnel for maintenance.
1.15.6.
Alarm due to (optional) Remote Control connection malfunction
The boiler recognises whether or not there is a Remote Control (optional).
If the boiler does not receive information from the Remote Control after the Remote Control itself is connected, the boiler attempts to re-establish
communication for 60 seconds, after which the fault code E31 is shown on the Remote Control display.
The boiler will continue to operate according to the settings on the touch screen panel and ignore the Remote Control settings.
Contact a Service Centre or a qualified service engineer to carry out the maintenance.
The remote control can indicate faults or shut-down conditions and can also restore boiler operation after shut-down up to a maximum of 3 times
in a 24 hour period. If the maximum number of attempts is reached, fault code E99 is shown on the boiler display. To reset error E99, disconnect
and re-connect again boiler from/to power mains.
1.16. Maintenance
The boiler must be serviced periodically as indicated in the relevant section of this manual.
Appropriate boiler maintenance ensures efficient operation, environment preservation, and safety for people, animals and objects.
Any maintenance (and repair) work must only be carried out by qualified personnel.
The user is strongly advised to have the boiler serviced and repaired by a qualified Service Centre.

Notes for the user
The user may only access parts of the boiler that can be reached without using special equipment or tools. The user is not authorised to
remove the boiler casing or to operate on any internal parts.
No one, including qualified personnel, is authorised to modify the boiler.
The manufacturer shall not be held responsible for damage to people, animals, or property due to tampering with or improper intervention
to the boiler.
If the boiler remains inactive and the power supply is switched off for a long time, it may be necessary to reset the pumps.
This involves removing the casing and accessing internal parts, so it must only be carried out by suitably qualified personnel.
Pump failure can be avoided by adding to the water filming additives suitable for multi-metal systems.
