PROGRAMMING THE P.C.B.

The 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 specific 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:

heating setting
The 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 off of the burner is correlated to the adjustment of the
domestic hot water temperature. In OFF mode, the burner is switched off at
maximum value.
The setting of this function is used to adjust the boiler so that it can operate
with the correct type of gas
The boiler is set to switch-on 3 seconds after the request. In the event of
particular systems (e.g. area systems with motorised thermostatic valves
etc.) it may be necessary to delay ignition
This function reduces the heating temperature to 57°C in the case that
domestic hot water circulation is detected in the heating mode.
With the post-circulation function active after domestic hot water withdra-
wal, the pump remains on for 2.5 seconds in winter time and 1.5 seconds in
summer time to reduce the formation of limestone.
The boiler also has electronic modulation that adapts the boiler potentiality
to the effective heating demand of the house. Then the boiler works nor-
mally in a variable gas pressure field 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.
The boiler has electronic timing, which prevents the burner from igniting
too often in central heating mode
In the ignition phase, the boiler performs an ignition ramp in order to
arrive at the maximum nominal power set (P06).

Defines the minimum flow temperature
- adjust the corresponding value consulting the table using keys
(5) and (6): first pressure of buttons displays the current value;
- confirm the value set by pressing the Reset button (1) for about
5 seconds. Only the displayed value is saved.
N.B.: 2 minutes after no button is touched will automatically
cancel the operation or by pressing buttons (1) and (2) simulta-
neously for about 5 seconds. Modified but not confirmed values
are to be restored to the value preceding the modification.
