• wait until the parameter b02 appears (adjustment of the boi-
ler nominal heat output).
The boiler starts up in heating mode; if you wish to adjust
the D.H.W., open a hot water tap after the burner goes on.
• Adjust parameter b02, observing the maximum pressure va-
lues stated in the tables (Parag. 4.1) depending on the type of
gas;
• press the button ( ) to increase the thermal power and but-
ton ( ) to decrease it.
• after the adjustment, press and hold the reset button (
)
to save the parameter. Confirmation that the parameter has
been saved is given by the value flashing.
If during the adjustment phase the value of the nominal
heat output of the boiler is exceeded by 0.2 mbar (pa-
rag. 4.1)table it is necessary to exit and re-enter from the
calibration phase to re-adjust.
- Adjustment of boiler minimum thermal heat output.
• press button ( ) or ( ) to select parameter b01 (minimum
boiler heat output during D.H.W.).
Only proceed after having calibrated the boiler nominal
heat output.
• press the button ( ) to increase the thermal power and but-
ton ( ) to decrease it.
• after the adjustment, press and hold the reset button (
)
to save the parameter. Confirmation that the parameter has
been saved is given by the value flashing.
Calibration correction
No active requests for central heating or D.H.W. pro-
duction must be present and the boiler must not be in
“Stand-by” mode.
The procedure described below allows the parameters set with the
"Complete calibration" to be partially changed.
Access the valve calibration function.
If parameter P15 has recently been set to 5 (e.g. for full gas valve
calibration), a different value must be set to access the "Calibration
correction".
- Correction of boiler nominal heat output calibration.
• Press buttons (
) and ( ) simultaneously for 5 seconds
until ''Ma'' + "nu" appears alternately on the display.
Press buttons (
) and ( ) again for 5 seconds or
wait 2 minutes without implementing any adjustment to
exit from the complete calibration phase.
• wait until the parameter b02 appears (adjustment of the boi-
ler nominal heat output).
The boiler starts up in heating mode; if you wish to adjust
the D.H.W., open a hot water tap after the burner goes on.
• Adjust parameter b02, observing the maximum pressure va-
lues stated in the tables (Parag. 4.1) depending on the type of

- Correction of boiler minimum heat output calibration:
• press button ( ) or ( ) to select parameter b01 (minimum
boiler heat output during D.H.W.).
• press the button ( ) to increase the thermal power and but-
ton ( ) to decrease it.
• after the adjustment, press and hold the reset button (
