1.11.5. Alarm caused by the temperature probes failure
If the burner gets blocked due to the water temperature probe malfunction, the display shows the codes:
-
E05
for the heating probe.
In this case the boiler does not work.
-
E04
for domestic hot water probe.
In this case the domestic hot water function is performed with modulation on the heating sensor.
-
E16
for the return line probe.
In this case the boiler continues to run.
In all four cases contact an Authorized Service Centre or personnel qualified for maintenance.
1.11.6. Blocking caused by the malfunction of the fan
The fan operation is constantly monitored; in case of burner malfunction, the fan is switched off and the flashing code
E15
is displayed on
the screen.
This status stays the same until the fan returns to normal operating parameters.
If the boiler does not resume operation and remains in this condition, contact an Authorized Service Centre or personnel qualified
for maintenance
.
1.11.7. Alarm due to a faulty connection to the remote control (option)
The boiler acknowledges the presence of the remote control (option not required).
If the remote control is connected and subsequently the boiler does not receive information from it, the boiler attempts to re-establish
communication for a period equal to 60 seconds; after this time has lapsed, on the remote control screen is displayed the code
E43
.
The boiler will keep running according to the settings made on the control panel, ignoring the settings made on the remote control.
In this case please contact an Authorized Service Centre or personnel qualified for maintenance.
1.12. Maintenance

1.13. Notes for the user
The user has free access only to the boiler parts whose operation does not require the use of tools and/or equipment; it is, there-
fore, not permitted to remove the boiler panel to intervene on its inner parts.
Nobody, including the qualified staff, is authorized to make changes to the boiler.
The manufacturer declines any liability for damage to persons, animals and objects generated by having tampered with the boiler

If the boiler remains inactive and disconnected from the power supply for a long time, the pump could require being unblocked.
This operation, which involves disassembling of the panel and the access to the boiler inner parts, must be performed by qualified
personnel.
The pump blocking can be avoided if the system is subjected treatment with specific protective products, suitable for systems
made from several metals.
