3.5 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 phase, press the
"Summer/Winter" (4) and "Reset" (5) buttons
simultaneously for 8 seconds.
once the menu has been accessed, it is possible
to scroll through the three sub-manus present
(s, p, t) by pressing the "Summer/Winter" (4)
button for 2 seconds.

To exit the menu, press the "Summer/Winter"
button (4) again for 4 seconds or wait for 120
seconds.
With the menu active on the indicator (17) the
parameter n° is displayed while indicator (21)
displays the parameter value.
Use the "DHW regulator" selector (2), to select
the parameter and rotate the "CH regulator"
(1) to modify the value according to the range
available.
With the menu active on the indicator (17) the
parameter n° is displayed while indicator (21)
displays the parameter value.
Press the "Reset" button (5) for 2 seconds to
memorise the variation of the parameters
The boiler also has electronic modulation that adapts the boiler potentiality to the effective
heating demand of the house. Then the boiler works normally in a variable gas pressure
field between the minimum heating power and the maximum heating power depending
on the system's heating load.
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 changeable using
parameter (S1).
N.B.: the selection of the "Minimum heating power" and "Maximum heating power"
parameters, in the presence of a heating request, allows switch-on of the boiler and po-
wer supply of the modulator with current equal to the value of the respective set value.
The setting of this function is used to adjust the boiler in order to function with the
correct type of gas
