Boiler functions

GREEN C.S.I.:

Semi-automatic filling

The boiler features a semi-automatic filling device
which turns on by pressing the
corresponding symbol
28).
If this condition occurs it means that the system is
incorrectly pressurised though the boiler will continue to
work regularly.
Press the circuit filling button
sequence.
Press the circuit filling button
interrupt the filling sequence.
During filling, the drops of the circuit filling 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. 30b); if it falls below a minimum
safety value (0.3 bar), fault code 41 appears on the
display (fig. 30a) 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
to start filling the circuit.
If you have to fill the system several times, contact
the Technical Service Centre to check whether the heating
circuit is watertight (see if there are any leaks).
GREEN R.S.I.:

Filling the circuit

If circuit pressure reaches 0.6 bar, the pressure value
flashes on the display (fig. 30b); if it falls below a minimum
safety value (0.3 bar), fault code 41 appears on the
display (fig. 30a) 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
circuit until the pressure value on the transducer ranges
between 1 and 1,5 bars.
If you have to fill the system several times, contact
the Technical Service Centre to check whether the heating
circuit is watertight (see if there are any leaks).
