3.4 INFORMATION MENU.
Pressing the buttons (3 and 4) for 5 seconds, the
“Information menu” is activated, which allows
to display some boiler functioning parameters.
To scroll through the various parameters, press
(3 and 4), to exit from the menu press buttons
(3 and 4) again for 5 seconds or press button (2)
for 5 seconds or wait for 60 seconds.
List of parameters.

d4
Displays the temperature set for
the central heating set (if remote

If the temperature is below zero,
the value is displayed ashing.
3.5 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, proceed as
follows:
- press keys (1) and (2) at the same time for
approximately 8 seconds;
- Using keys (3) and (4), select the parameter to
be changed indicated in the following table:

parame-
ters
Description
P1 Boiler mode (DO NOT USE)
P2 Display lighting
P3 DHW thermostat
P4 Minimum CH output
P5 Maximum CH output
P6 Central heating ignitions timer
P7 Central heating ramp timer
P8
Heating switch-on delay
request from room thermostat
and remote control.
P9 Solar mode
- adjust the corresponding value consulting the
table using buttons (5) and (6);
- confirm the set value pressing the Reset
button (1) for approximately 3 seconds; by
pressing keys (3) + and (4) - at the same time
exit the function without memorising the
modications made.
N.B.: aer a period of time, without touching
any keys, the operation cancels automatically.
Boiler mode. It establishes whether the boiler
functions in instant or storage mode.
Boiler mode (P1)
Range of values which can
be set
Standard
setting
0 - instant boiler
1 - Boiler with storage tank
0
Display lighting. Establishes the display lighting
mode:
Display lighting (P2)
Range of values which can
be set
Standard
setting
0 - O
1 - Auto
2 - On
1
- O: the display is always lit with low intensity.
- Auto: the display lights up during use and
lowers aer 15 seconds of inactivity. In the case
of anomaly the display ashes.
- On: the display is always lit with high intensity.
DHW thermostat. With the “correlated”
thermostat setting, boiler switch-o takes place
on the basis of the temperature set. While with
the setting of the "xed" DHW thermostat the
switch-o temperature is xed at the maximum
value independently from the value set on the
control panel.
DHW thermostat (P3)
Range of values which can
be set
Standard
setting
0 - Fixed
1 - Correlated

Heating output. e boiler also has electronic
modulation that adapts the boiler potentiality
to the eective heating demand of the house.
en the boiler works normally in a variable
gas pressure eld between the minimum heating
output and the maximum heating output
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, which can be changed
using the parameter (P5).
N.B.: the selection of the “Minimum heating
output” and “Maximum heating output”
parameters, in the presence of a heating request,
allows switch-on of the boiler and power supply
of the modulator with current equal to the value
of the respective set value.
Minimum central heating output (P4)
Range of values which can
be set
Standard
setting
0 - 63 %
Set
according
to factory
inspection
Maximum heating output (P5)
Range of values which can
be set
Standard
setting
0 - 99 % 99
Central heating ignitions timer. e boiler has
electronic timing, which prevents the burner
from igniting too oen in central heating mode.
Central heating ignitions timer (P6)
Range of values which can
be set
Standard
setting
0 - 20 (0 - 10 minutes)
(01 equals 30 seconds)

(3’)
Central heating ramp timing. In the ignition
phase, the boiler performs an ignition ramp in
order to arrive at the set maximum output.
