Filling the circuit
If circuit pressure reaches 0.6 bar, the pressure value flashes on the display
(Fig. 14); if it falls below a minimum safety value (0.3 bar), fault code 41
appears on the display (Fig. 15) for a certain time, following which, if the
fault persists, fault code 40 is displayed (see chapter on "Troubleshooting").
In the event of faul 40 (Fig. 16) proceed as follow to restore the correct
pressure value:
- press button
- open the filling tap external to the boiler, until the pressure shown in the
display is between 1 and 1,5 bar.
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

Info list:
Info 0 - shows the word InFO (Fig. 17)
Info 1 - only with the external probe connected, displays external temperature
(e.g. 12°C) (Fig. 18). The values shown on the display range between - 30°C
and 35°C. Beyond these values the display shows "- -"
Info 2 - shows circuit pressure (Fig. 19)
Info 3 - shows the set heating temperature (Fig. 20)
Info 4 - shows the setted temperature (only water tank with sensor, Fig. 21)
Info 5 - displays the set heating temperature, in reference to the second
circuit, only if it is connected.

It is possible to display information, which may be useful for the Technical
Assistance Centre, by pressing the button

S.A.R.A. function (Fig. 22)
If the "winter" mode is selected, the S.A.R.A. function is activated for the
heating circuit. This function allows to reach the required ambient tempe-
rature more quickly.
Depending on the temperature set on the ambient thermostat and the time
taken to reach it, the boiler automatically adjusts the heating water tem-
perature to reduce operating times, thereby increasing operating comfort
and energy saving.
