VALUE CHECK, the FRONT PANEL must be CLOSED
and the INTAKE/FUME EXHAUST DUCTS completely
assembled. Also, the boiler must not be in OFF mode
(see detail C of fig. 11) and there must be no heating
or DHW circuit request.
Calibration procedure [AUTO SETUP]
1. Access the

up]
is also displayed.
4. Select it and confirm with the button .
5. The procedure starts automatically find-
ing the optimal ignition point.
6. After ignition, the burner goes to the vari-
ous powers (max, med, min) indicated by
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 not successful, the display shows

.
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
• when fault conditions
A01
,
A06 occur or in other faults when required
(see table 11. Re-
spect the sequence of fault solutions).
