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 212 ***).
3. By means of a combustion analyzer, connected to the points located on the starting accesso-
ries 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.
100% calibration, manual
Calibration procedure
.
• Put the boiler (preferably) in heating mode or else in DHW mode.
• Access the user menu
• Access the [
service menu] and press confirm
• Enter the password
"1234"
and confirm [
]
• Select [Combustion Control]
• Select the parameter [15/100% Calibration]
• Enter "1"
• Press OK to confirm
• 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]
.
