Checking the combustion values
MAKE SURE THE FRONT CASING IS CLOSED AND THE INTAKE/FUME EXHAUST DUCTS ARE COMPLETELY
ASSEMBLED.
1. Put the boiler in heating or DHW mode for at least 2 minutes. During this period if the flame symbol flashes on the
display, it means that the boiler is performing a calibration. Wait until the flame becomes steady (end of calibration).
2. Activate the TEST mode (see *** 'TEST mode activation' on page 205 ***).
3. By means of a combustion analyzer, connected to the points located on the starting accessories above the boiler,
check that the CO2 content in the fumes, with boiler working at maximum and minimum output, matches that given
in the following table.
4. If the combustion values do not match, do the
100% calibration
as described in the following paragraph.
5. If the values still do not match, do not activate other calibrations as the system needs to work longer to be able to
self-adapt
.
100% calibration
IMPORTANT: DURING THE AUTOMATIC CALIBRATION PROCEDURE AND CHECK OF THE CO
2
VALUE, THE
FRONT CASING OF THE BOILER MUST BE CLOSED AND THE INTAKE/FUME EXHAUST DUCTS COMPLETELY
ASSEMBLED.
100% calibration, automatic
Automatic calibration can take place in some cases in the absence of a DHW or heating demand or after a reset due to
a fault and is indicated on the display by the flashing flame symbol.

The main screen will appear with the flashing flame icon until the end of calibration.
Loading parameters with “BCC KEY”
The
“BCC KEY”
device allows the updating of combustion parameters for boiler type.
It is used in case of replacement of the PCB of some boiler models.
To use the
“BCC KEY”
, refer to the instructions contained in the
kit code [NUOVO CODICE]
.
TEST mode activation
•
Access the [

and confirm [
]
•
Press [Test Mode]. The display shows the operating information.
•
Burner power can be increased or decreased by touching [+] and [-].

Wait about 1 minute for the values to stabilize
Test mode remains active as long as the user stays on the corresponding screen. It is automatically deactivated on exi-
ting the screen or after 20 minutes of user inactivity.
