Calibration procedure [AUTO SETUP]
1. Access the parameters menu[TSP].
2. Select parameter b27 with the
ting buttons and set it to 5 with the
DHW buttons.
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 Setup] is
also displayed.
4. Select it and confirm with the button
5. The procedure starts automatically finding the op-
timal ignition point (a few ignition attempts are re-
quired to determine the exact point).
6. After ignition, the burner goes to heating at the va-
rious powers (max, med, min) indicated by point
a
(fig. 41).
If the system heat dissipation is not sufficient to
end the procedure, a DHW request can be activa-
ted only after the burner has ignited.
7. At the end of the calibration sequence [Comple-
ted] will be displayed for a few seconds and then
return to the Service menu.
8. If the ignition sequence described in point "6" is
not successful, the message max_err at point
and an error code at point
9. Exit with the button
Repeat the sequence from point "1".
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 by:
• changing the parameter "gas type" b03.
• setting parameter P67 to 1.
• changing the value of parameter P68.
• doing "Restore Factory Values" with the parameter b29=10 (after carrying out this operation, disconnect and re-
connect the power supply for about ten seconds).
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
cures).
The calibration procedure [Auto Setup] resets the combustion parameters previously recorded and must be done
only in the cases described above.
