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.
N°
parameter
Description
d1 Displays the ame signal (uA).
d2
Displays the primary exchanger
output instant heating ow
temperature.
d3
Displays the instant output
temperature from the DHW
exchanger.
d4
Displays the temperature set for
the central heating set (if remote
control is present).
d5
Displays the temperature set for
the DHW set (if remote control
is present).
d6
Displays the external environ-
ment temperature (if the exter-
nal probe is present).
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 buttons (1) and (2) at the same time for
approximately 8 seconds;
- Using buttons (3) and (4), select the parameter
to be changed indicated in the following table:

eters

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);
- conrm the set value pressing the Reset button
(1) for approximately 3 seconds; by pressing
keys (3) and (4) at the same time exit the func-
tion 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
Illumination display. Determines how display
illumination.
Display lighting (P2)
Range of values which can
be set
Standard
setting
0 - O
1 - Auto
2 - On

- O: the display is always lit with low intensity.
- Auto: the display lights up during use and low-
ers 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” ther-
mostat 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 pres-
sure eld 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, which can be changed
using the parameter (P5).
N.B.: the selection of the “Minimum heating
power” and “Maximum heating power” param-
eters, 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

Central heating ignitions timer. e boiler has
electronic timing, which prevents the burner
from igniting too oen in central heating mode.

Central heating ramp timing. In the ignition
phase, the boiler performs an ignition ramp in
order to arrive at the maximum power set.
