3.8 PROGRAMMING THE P.C.B.
e boiler is prepared for possible programming
of several operation parameters. By modifying
these parameters as described below, the boiler
can be adapted according to specic needs.
To access the programming phase, position the
DHW selector (5) (Fig. 2-1) on position “6”, the
CH selector (6) on position “9” and press the
“Reset” (3) and “Summer/Winter” buttons for
about 8 seconds (2).
Once the menu has been accessed, it is possible
to scroll through the three sub-menus present
(s, p, t) by pressing the “Summer/Winter” (2)
button for 1 second.
Use the “DHW regulator” selector (5), to select
the parameter (inside the same sub-menu) and
rotate the “CH regulator” selector (6) to modify
the value according to the range available.
Press the “Reset” button (3) for 1 second to
memorise the variation of the parameters.
Memorisation is represented via “88” on the
indicator (14) for 2 seconds.
Exit the programming mode by waiting for
15 minutes or by pressing the, “Reset” (3) and
“Summer/Winter” (2) buttons simultaneously.

Parameter Description Range Default
S0
Minimum DHW
output
e boiler also has electronic modulation that adapts the boiler potentiality to the ef
-
fective heating demand of the house. erefore the boiler works normally in a variable
gas pressure eld between minimum and maximum power depending on the system
heat load, setting fan speed (in rpm, hundreds of revs are represented on the display).
N.B.:the boiler is produced and calibrated in the central heating phase at nominal
output. Approximately 10 minutes are needed to reach the nominal heat output, which
can be changed using the parameter (S3).
N.B.: selection of parameters in the presence of requests, allows boiler functioning with
current equal to the respective value.

correction
If the reading of the external probe is not correct it is possible to correct it in order to
compensate any environmental factors.
