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, rotate the function selector to
adjust the filling tap until the pressure reaches a value between 1
and 1.5 bar.
Then rotate the mode selector to the desired position
or
(winter).
If pressure drops are frequent, request the intervention of the Tech-
nical Assistance Service.
Fault A06
The boiler operates normally but cannot reliably maintain a con-
stant 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 down-
stream the gas valve and connecting the pressure gauge
- disconnect the compensation inlet of the air distribution box
4.5.1 Maximum power and minimum domestic hot water adjust-
ment
- 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

- 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
(winter
G20 and 165 mA for LPG).
- carefully prise out the protection cap of the adjustment screws,
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
- 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.
4.5.2 Minimum and maximum heating electric adjustment
The "electric adjustment" function is activated and deactivated
exclusively by the jumper (JP1) (fig. 16).
The two LEDs (GREEN and RED) on the control panel flash simul-
taneously for approximately 4 seconds.
The function can be enabled in the following way:
- by powering the card with the jumper JP1 inserted and the mode
selector in winter position, independently from the possible pres-
ence of other operation request.
- by inserting the jumper JP1, with the mode selector in winter posi-
tion, without heat request in progress.
By activating the function the burner is ignited through simula-
tion of heat request in heating.
To perform calibration operations, proceed as follow:
- switch off the boiler
- remove the shell and access the card
- insert the jumper JP1 (fig. 16) to enable the knobs placed on the
control panel to the minimum and maximum heating adjustment
functions.
- make sure that the mode selector is in winter position (see section
4.2).
- power the boiler
