Switching off for long periods
In case of absence for long periods of time, set the mode selector ( fi g. 31) to
(OFF). Turn the main system switch OFF. Close the fuel and water taps
of the heating and domestic hot water system. In this case, anti-frost device
is deactivated: drain the systems, in case of risk of frost.
4.3 Light signals and faults
To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector to (OFF), wait 5-6 seconds then set it to
the required position (summer mode) or (winter mode).
If the reset attempts do not reactivate the boiler, contact the Technical As-
sistance Centre.
Fault A 04
In addition to the fault code, the digital display shows the symbol .
Check the pressure value indicated by the water gauge:
if it is less than 0.3 bar, position the function selector to (OFF) and adjust
the
fi lling tap until the pressure reaches a value between 1 and 1.5 bar.
Then position the mode selector to the desired position (summer) or
(winter). The boiler will perform one purge cycle lasting approximate-
ly 2 minutes. If pressure drops are frequent, request the intervention of the
Technical Assistance Service.
Fault A 06
Contact the Technical Assistance Centre.
Fault A 07

Fault A 09 with fi xed red LED lit
Position the function selector to (OFF), wait 5-6 seconds then set it to the
required position (summer mode) or (winter mode).
If the reset attempts do not reactivate the boiler, request the intervention of
the Technical Assistance Service.
Fault A 09 with fl ashing red and green LEDs
The boiler is equipped with an auto-diagnostic system which, based on the
total number of hours in certain operating conditions, can signal the need
to clean the primary exchanger (alarm code 09 with
fl ashing red and green
LEDs and fl ue gas meter >2,500).
Once the cleaning operation has been completed, using the special kit sup-
plied as an accessory, the total hour meter will need to be reset to zero as
follows:
- switch off the power supply
- remove the housing
