3.12 PROGRAMMING THE P.C.B.
The boiler is prepared for possible programming
of several operation parameters. By modifying
these parameters as described below, the boiler
can be adapted according to specific needs.
To access the programming stage, set the DHW
selector in the “6 o' clock” position and the heat-
ing selector in the “9 o' clock” position and press
the “Reset” and “Summer/Winter” buttons for
about 8 seconds (Fig. 3-13).
Once the programming mode has been accessed,
scroll through the five menus (G, P, t, A, F) by
pressing the “Summer / Winter” button for 1
second.
Use the ''D.H.W. regulator'' selector to select
the parameter (within the same sub-menu)
and rotate the ''C.H. regulator'' selector to alter
the value.
Press the "Reset" button for 1 second to store the
altered parameters.
Memorisation is represented via "88" on the
indicator (Ref. 14 Fig. 2-1) for 2 seconds.
Exit the programming mode by waiting for 15
minutes or by pressing the “Reset” and "Summer/
Winter" buttons at the same time.
Attention:
if necessary the default values relating
to parameters “S” and “P0 ÷ P2” can be altered by
temporarily modifying the type of gas (parameter
“G”) and by restoring it according to the actual
operating conditions (wait for approximately 10
seconds between the gas change and the when
it is restored).
3-13
The restored values will be those relating to the
type of boiler set in parameters “n” and “F”.
At the end of this operation, anomaly “E62” will
appear and complete calibration will be required.

Menu “G”.
This menu is reserved for the air-gas
control settings and it features two sub-menus
(n and S), relating to fan and gas valve control
settings. Every time these parameters are al-
tered, the complete calibration function must
be activated (see par. 3.8). In order to access
parameters “n” and “S” press the “Reset” button
sequentially. In order to exit this part of the
menu and access other parts (categories P, t,
A, F) press the “Summer / winter” button.
