This new temperature value is the result of the temperature set
manually with the heating water temperature selector and the
increase of +10 °C of the S.A.R.A function. After the second cycle
the temperature value should be kept at the set value +10°C until
the request of the room thermostat is satisfied.
4.3 Switching off
Temporary switching off
In case of absence for short periods of time, set the mode selector
(fig 6b) to
(OFF), the green LED flashes ON for 0.5 seconds,
OFF for 3.5 seconds.
In this way (leaving the electricity and fuel supplies enabled), the
boiler is protected by the following systems:
- Anti-frost device: when the temperature of the water in the
boiler falls below 5°C, the circulator and, if necessary, the
burner are activated at minimum output levels to bring the water
temperature back to the values for safety (35°C). During the anti-
frost cycle, the symbol
- Circulator anti-blocking function: an operation cycle is
activated every 24 hours.
Long period switching off
In case of absence for long periods of time, set the mode selector
(fig 6b) to
(OFF), the green LED flashes ON for 0.5 seconds,
OFF for 3.5 seconds.
Turn the main system switch OFF. Close the gas and water taps of
the heating and domestic hot water system. In this case, anti-frost
device is deactivated: drain the systems, in case of risk of frost.
4.4 Light signals and faults
The operating status of the boiler is shown on the digital display,
below is a list of the types of displays.
To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector to
set it to the required position
mode). If the reset attempts do not reactivate the boiler, contact the
Technical Assistance Centre.
Fault A04
In addition to the fault code, the digital display shows the symbol
Check the pressure value indicated by the water gauge:
if it is less than 0.3 bar, position the function selector to
and adjust the filling tap (L - fig. 13) until the pressure reaches a
value between 1 and 1.5 bar.
Then position the mode selector to the desired position
(summer) or
(winter).
If pressure drops are frequent, request the intervention of the
Technical Assistance Service.

Fault A06
The boiler operates normally but cannot reliably maintain a
constant domestic hot water temperature, which remains set at
around 50°C. Contact the Technical Assistance Centre.
Fault A07
Contact the Technical Assistance Centre.
4.5 Adjustments
The boiler has already been adjusted by the manufacturer.
If it is necessary to adjust it again, for example after extraordinary
maintenance, after replacement of gas valve or after gas
conversion, carry out the following procedure.
The maximum output adjustment must be carried out in the
sequence indicated exclusively by qualified personnel.
- remove the shell unscrewing the fixing screws A (fig. 6)
- unscrew by two turns the screw of the pressure test point
downstream the gas valve and connecting the pressure gauge.
4.5.1 Maximum power and minimum domestic hot water
adjustment
- Fully open the hot water tap
- On the control panel:
- set the mode selector to
- turn the domestic hot water temperature selector to its
maximum (fig. 8a)
- Power the boiler setting the system main switch to "on"
- Check that the pressure on the pressure gauge is stable; or with
a milliammeter in series to the modulator, make sure that the
modulator supplies the maximum available current (120 mA for
G20 and 165 mA for LPG).
- Carefully prise out the protection cap of the adjustment screws,
(winter
using a screwdriver (fig. 15)
- With a fork spanner CH10 use the adjustment nut of the maximum
output in order to obtain the value indicated in table "Technical
data"
- Disconnect the modulator faston
.
- Wait until the pressure on the pressure gauge is stable at
minimum value
(OFF)
- Paying attention not to press the internal shaft, use an Allen
spanner to turn the red adjustment screw for domestic hot water
minimum temperature regulation, calibrating it until the pressure
gauge reads the value indicated in the table "Technical data"
- Reconnect the modulator faston
- Close the domestic hot water tap
- Carefully refit the protection cap of the adjustment screws.
