Calibration procedure [AUTO SETUP]
1. Access the parameters menu[TSP].
2. Select parameter b27 with the
heating buttons and set it to 5 with the
and 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 Set-
up] is also displayed.
4. Select it and confirm with the button
5. The procedure starts automatically find-
ing the optimal ignition point (a few igni-
tion attempts are required to determine
the exact point).
6. After ignition, the burner goes to heating
at the various powers (max, med, min) in-
dicated by point
If the system heat dissipation is not suffi-
cient to end the procedure, a DHW re-
quest can be activated only after the
burner has ignited.
7. At the end of the calibration sequence
[Completed] will be displayed for a few
seconds and then return to the Service
menu.
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 reconnect 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.
