Working the boiler
Adjust the ambient thermostat to the required temperature (approx.
20 °C). If there is a demand for heating water, the boiler starts
and the symbol is shown on the display (fig. 24). The boiler will
remain working until the set temperatures are reached, after which
it will go on stand-by. In the event of ignition or operating faults,
the boiler will perform a "safety stop".
The flame symbol will go out and the fault code and
be displayed (fig. 25). For a description of faults and how to reset
them, consult chapter "Troubleshooting".

Switching off

Switching off for short periods
For brief absences press the
display will show two segments in the central area (fig. 17). When
the boiler remains powered with the gas tap open, it is protected
by the following systems:
- anti-freeze (fig. 26): when the temperature of the water in the
boiler falls below safety values, the circulator and the burner
work at minimum power to increase the water temperature to a
safe value (35 °C). The

- circulator anti-block: one operating cycle is performed every
24 hours.
Switching off for long periods
For prolonged absences press the
(fig. 17). The display will show two segments in the central area.

symbol and the growing pressure value appear on the
display in a cascade sequence (fig. 29).

After filling, the symbol is displayed for a few moments and then
turns off.
Note
During filling, the boiler does not perform other functions. For
example, if there is a request for domestic hot water, the boiler is
unable to provide it until filling has finished.
Note
If circuit pressure reaches 0.6 bar, the pressure value flashes on
the display (fig. 30a); if it falls below a minimum safety value (0.3
bar), fault code 41 appears on the display (fig. 30b) for a certain
time, following which, if the fault persists, fault code 40 is displayed
(see chapter on "Troubleshooting").

In the event of fault 40, press
