N.B. If the attempt to reset the appliance does not activate operation, con-
tact the Technical Assistance Service.
3a SWITCHING OFF
Temporary switch-off
In case of absence for short periods of time, set the mode selector (fi g. 32)
to (OFF). In this way (leaving the electricity and fuel supplies enabled),
the boiler is protected by:
Anti-frost device: when the temperature of the water in the boiler falls be-
low 5°C, the circulator and, if necessary, the burner are activated at mini-
mum output levels to bring the water temperature back to the values for
safety (35°C). During the anti-frost cycle, the symbol (fi g. 36) appears
on the digital monitor.
Circulator anti-blocking function: an operation cycle is activated every 24
hours.
Switching off for long periods
In case of absence for long periods of time, set the mode selector (fi g. 32)
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.
4a LIGHT SIGNALS AND FAULTS
The control panel has three LEDs that indicate the boiler operating status:
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 (fi g. 32)
and adjust the fi lling tap (C- fi g 17) until the pressure reaches a value be-
tween 1 and 1.5 bar. Then position the mode selector to the desired posi-
tion (summer) or (winter). The boiler will perform one purge cycle
lasting approximately 2 minutes. If pressure drops are frequent, request
the intervention of the Technical Assistance Service.
Fault A 06
The boiler operates normally but cannot reliably maintain a constant do-
mestic hot water temperature, which remains set at around 50°C. Contact
the Technical Assistance Centre.
Fault A 07 - A 08
Contact the Technical Assistance Centre.
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.
