(see detail C of fig. 11) and there must be no heating
or DHW circuit request.
Calibration procedure [AUTO SETUP]
1.Access the parameters menu[TSP].
2.Select parameter b27 with the buttons
and Heating and set it to 5 with the
buttons and
Confirm with the button
Return to the main menu[MENU].
3.Return to the installer menu [Service]
>enter the Password 1234 (see fig. 17).
Now the menu for calibration[Auto Set-
up] is also displayed.
4.Select it and confirm with the button
5.The procedure starts automatically finding
the optimum ignition point.
6.After ignition, the burner goes to the vari-
ous powers (max, med, min) indicated by
the point (fig. 38).

7.At the end of the sequence the display re-
turns to the Service menu
8.If the ignition sequence described in point
"6" is unsuccessful, the display shows
the message max_err at the point
and an error code at the point
(fig. 38).
The calibration procedure [Auto Setup] can only be performed if parameter b27 is set to 5.
Parameter b27 can be set manually to the value 5 or as follows:
•by changing the parameter "gas type" b03.
•by setting parameter P67 to 1.
•by changing the value of parameter P68.
•by "Restore Factory Values" with parameter b29=10.
In each of the above cases, b27 automatically changes to 5.
It is necessary to perform the calibration procedure [Auto Setup] in the following cases:
•after replacing the PCB
•after changing the gas (b03)
•setting parameter P67 to 1
•after changing the value of parameter P68
•after setting parameter b27 to 5 for replacement of components such as the electrode, burner,
gas valve, fan or for installations with maximum flue resistance
•in case of fault conditions A01, A06 or other faults when required (see table 11. Respect the
sequence of fault solutions).
The calibration procedure [Auto Setup] resets the combustion parameters previously recorded
and must be done only in the cases described above.
