3.11 PROGRAMMING THE P.C.B.

The boiler is prepared for possible programming of several op-
eration 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 (5) in
the "6" position and the heating selector (6) in the "9" position
and press the "Reset" (3) and "Summer/Winter" (2) buttons for
about 8 seconds.
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.

Description
The boiler also has electronic modulation that adapts the boiler poten-
tiality to the effective heating demand of the house. Therefore the boiler
works normally in a variable gas pressure field 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.
Defines the minimum flow temperature.
Defines the maximum flow temperature.
If the reading of the external probe is not correct it is possible to correct
it in order to compensate any environmental factors.
(Over the value of +9 the display shows "CE", which enables an external
control function of the boiler for coupling of the same with a system
supervisor)
Identifies the boiler s power (only useful with a coupled storage tank
and parameter P0=1).
Use the ''D.H.W. regulator'' selector (5) to select the parameter
(within the same sub-menu) and rotate the ''C.H. regulator''
selector (6) to modify the value according to the range available.
Press the "Reset" (3) button for 1 second to store the altered
parameters.
If the parameters are stored successfully, "88" appears 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 at the
same time.
