3.20 INFO menu
Press button 3 from the initial display screen to see a
series of information items relating to boiler operation,
listed according to the parameter name and value.
To switch between parameters, press the and
buttons. Press to see the selected parameter; press
to return to the main screen.
3.21 Temporary switch-off
In the event of temporary absences (weekends, short
breaks, etc.) set the status of the boiler to OFF .
The electricity supply and fuel supply remain active, so
the system is protected by:
heating anti-freeze: this function is activated if the
temperature measured by the ow sensor drops be-
low 5°C. A heat request is generated in this phase,
with burner ignition at minimum output and main-
tained at this level until the delivery water tempera-
ture reaches 35°C;
DHW anti-freeze (if water tank with probe): this
function is activated if the temperature measured by
the water tank probe drops below 5°C. A heat request
is generated in this phase, with burner ignition at
minimum output and maintained at this level until
the delivery water temperature reaches 55°C.

The activation of the ANTI-FREEZE function is sig-
nalled by a sliding message on the interface dis-
play: AF1 (DHW ANTI-FREEZE IN PROGRESS) or AF2
(HEATING ANTI-FREEZE IN PROGRESS), depending on
the situation.
circulator anti-blocking: the circulator activates every
24 hours of stoppage for 30 seconds.
