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 flame signal (uA)

d2

Displays the primary exchanger 

output instant heating flow 

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 

environment temperature

(if the external probe is present)

If the temperature is below zero, 

the value is displayed flashing.

3.5  PROGRAMMING THE P.C.B.

The boiler is prepared for possible programming 

of several operation 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:
- 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:

- 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 

modifications made.

N.B.:

 after 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

Display lighting.

 Establishes the display lighting 

mode:

Display lighting (P2)

Range of values which can 

be set

Standard 

setting

0 - Off 

1 - Auto

2 - On

1

- Off:

 the display is always lit with low intensity.

- Auto:

 the display lights up during use and 

lowers after 15 seconds of inactivity. In the case 

of anomaly the display flashes.

- On:

 the display is always lit with high intensity.

DHW thermostat.

 With the setting of the do-

mestic hot water thermostat on “Hysterisis 1” 

the boiler ignites to heat the domestic hot water 

when the water contained in the storage tank 

unit falls by 3°C with respect to the temperature 

set, while on “Hysterisis 2” ignition takes place 

when the water contained in the storage tank unit 

falls by 10°C with respect to the temperature set.

DHW thermostat (P3)

Range of values which can 

be set

Standard 

setting

0 - Hysteresis 1  

(Standard setting)

1 - Hysteresis 2

0

Heating output.

 The boiler also has electronic 

modulation that adapts the boiler potentiality 

to the effective heating demand of the house. 

Then the boiler works normally in a variable 

gas pressure field 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 %

 Maximum heating output (P5)

Range of values which can 

be set

Central heating ignitions timer.

 The boiler has 

electronic timing, which prevents the burner 

from igniting too often in central heating mode.

Range of values which can 

be set

Standard 

setting

0 - 20 (0 - 10 minutes)

Central heating ramp timing.

 In the ignition 

phase, the boiler performs an ignition ramp in 

order to arrive at the set maximum output.
