3.9 PROGRAMMING THE P.C.B.
e boiler is prepared for possible programming of several ope-
ration parameters. By modifying these parameters as described
below, the boiler can be adapted according to specic needs.
To access the programming phase, proceed as follows (references
Fig. 30).
- press buttons (1) and (2) for 5 about seconds until the program-
ming mode is accessed on the display;
- using keys (3) and (4), select the parameter to be changed indi-
cated in the following table:
- adjust the corresponding value consulting the table using keys
(5) and (6): rst pressure of buttons displays the current value;
- conrm the value set by pressing the Reset button (1) for about
5 seconds. Only the displayed value is saved.
N.B.: 2 minutes aer no button is touched will automatically
cancel the operation or by pressing buttons (1) and (2) simulta-
neously for about 5 seconds. Modied but not conrmed values
are to be restored to the value preceding the modication.

Solar panels
selection
e setting of this function is used to set the boiler in order to function
with the use of solar panels. By setting the parameter P0 in "solar"on
mode, the switching o of the burner is correlated to the adjustment of the
domestic hot water temperature. In OFF mode, the burner is switched o at
maximum value.

Minimum CH
output
e boiler also has electronic modulation that adapts the boiler potentiality
to the eective heating demand of the house. en the boiler works nor-
mally in a variable gas pressure eld between the minimum heating output
and the maximum heating output depending on the system's heating load.
NOTE: the boiler is produced and calibrated in the central heating phase at
nominal output. Approximately 10 minutes are needed to reach the nomi-
nal heat output, which can be changed using the parameter (P08).
NOTE: the selection of the “Minimum heating output” and “Maximum
heating output” parameters, in presence of a heating request, allows boiler
ignition and power supply of the modulator with current equal to the value
of the respective set value.
