Boiler functions
MIX C.S.I.:
Semi-automatic filling
The boiler features a semi-automatic filling device which
turns on by pressing the
button when the corresponding
symbol
is shown on the display (fig. 24).
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
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. 25).
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 falls below a minimum safety value (0.3
bar), fault code 41 appears on the display (fig. 26) 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
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).
MIX R.S.I.:
Filling the circuit
If circuit pressure falls below a minimum safety value
(0.3 bar), fault code 41 appears on the display (fig. 26)
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
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).
Information
Press
, the display turns off and just the word InFO
appears (fig. 27).
Press the button
to view operating information.
Press the button again to move on to the next piece of
information. If the
button is not pressed, the system
automatically exits the function.
Info list:
Info 0 shows the word InFO (fig. 27)
Info 1 only with the external probe connected, displays
external temperature (e.g. 12 °C) (fig. 28).
