- turn the domestic hot water temperature selector to change the
value (1 MTN - 2 LPG)
- press ENTER to confirm the new value. The digits stop flashing.
MAXIMUM POWER ADJUSTMENT (P. HH)
- Turn the domestic hot water temperature selector till HH is shown
- Use a fork spanner CH10 to turn the maximum power to the

- Wait for the pressure on the pressure gauge to stabilise at the
required value.
MINIMUM POWER ADJUSTMENT (P. LL)
- Turn the domestic hot water temperature selector till LL is shown
-
Taking care not to press on the inner shaft , turn the red
domestic hot water minimum adjustment screw with a
screwdriver until the pressure gauge reads the value indicated
in the multigas table.
MAXIMUM HEATING ADJUSTMENT POSSIBILITY (P. 23)
C.A.I.-MIX C.S.I.:
check that the pressure read on the pressure
gauge corresponds to that shown on the multigas table.
R.A.I.-MIX R.S.I.: check that the pressure read on the display is 255.
If it does not, carry out the adjustment operations described below:
- turn the domestic hot water temperature selector till 23 is shown.
Wait for the boiler to start
- press ENTER to access the parameter modification function
-
C.A.I.-MIX C.S.I.: turn the domestic hot water selector until the
pressure gauge corresponds to that indicated in the multigas table
- R.A.I.-MIX R.S.I.: turn the domestic hot water selector until the

- press ENTER to confirm the new value.
Exit the CALIBRATION & SERVICE function by pressing ESCAPE.
The boiler returns to the “- -” (OFF) status.
To reset, press the
button.
- Reconnect the compensation inlet to the air distribution box
(MIX C.S.I.-MIX R.S.I.)
- Disconnect the pressure gauge and tighten the pressure tap
screw.
After adjusting the gas valve, seal it with sealing wax.
After making adjustments:
- return the temperature set with the ambient thermostat to the
required position
- close the panel
- put back the shell.
The boiler has already been factory adjusted by the manufacturer.
For LPG gas: the boiler has been regulated in I3B/P category
(G30). If you need to regulate in I3+ or I3P categories (G31) exclude
pressure regulator.
If a new adjustment is required, for example, after extraordinary
maintenance, replacing the gas valve or converting from natural
gas to LPG, proceed as follows.
Maximum and minimum power, minimum and maximum
heating, must be adjusted in the indicated sequence by
qualified staff.
- Unscrew the lower cover fixing screw ( C , fig. 3c)
- Pull the cover towards you and remove ( A-B ) (fig. 4a)
- Loosen the two fixing screws ( D ) and remove the shell (fig. 3a)
- Lift up the panel and turn it forwards
- Loosen the pressure tap screw downline from the gas valve by
about two turns and connect the pressure gauge to it
- Carefully prise out the cap protecting the adjustment screws
with a screwdriver
- Disconnect the compensation inlet from the air distribution box
(MIX C.S.I.-MIX R.S.I., fig. 76)
CALIBRATION & SERVICE operations must be performed with
the boiler in the OFF position. To do this, press the
button
until the display shows “- -” (fig. 40 C.A.I. -MIX C.S.I.; fig. 72
R.A.I. - MIX R.S.I.).
During parameter modification operations, the “select
functions” button acts as an ENTER (confirm) button, the
button acts as an ESCAPE button. If no confirmation is given
within 10 seconds, the value is discarded and returns to the
previously set one.
Setting the password
Press and hold down the operating mode button and the button
together for about 10 seconds. The display will look like fig. 41
(C.A.I. -MIX C.S.I.) and fig. 73 (R.A.I. - MIX R.S.I.).
Enter the password for accessing the parameter modifications
function by turning the domestic hot water temperature selector to
the required value.
The password is located on the back side of the control panel.
Confirm by pressing ENTER.
Calibration phases
Turn the domestic hot water selector to sequentially scroll the
CALIBRATION & SERVICE phases:
- 1
gas type
- 2 boiler power (MIX C.S.I.-MIX R.S.I., parameter not used in
this phase)
- 10 domestic hot water mode (parameter not used in this phase)
- 3
insulation level of building (only if external sensor is
connected)
- 45 inclination of thermoregulation curve (OTC), only if external
sensor is connected)
- HH boiler at maximum power
- LL boiler at minimum power
- 23 maximum heating adjustment possibility
- 24 minimum heating adjustment possibility.
The parameters must be modified, by professionally
qualified personnel, only if absolutely necessary. The
manufacturer refuses any responsibility in the case of
incorrect setting of the parameters.
