OFFSET and SLOPE 100% calibration
With this procedure it is possible to do (if necessary) a fine setting on the automatic calibration that
the boiler performs. With this setting it is possible to raise or lower the entire combustion curve
and change the slope.
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

• Select the parameter
[15/100% calibration]
• Type
"3"
• Press
[OK]
to confirm
• The main screen will appear with the flashing flame icon and the message
[Calibration in pro-
gress].
• At the end of the calibration procedure, the display will show the screen relevant to the para-
meter
Sc12*
Modify the parameter with the + and – buttons.
After finding the correct operating point, press
[OK]
.
• The main screen will appear again with the flashing flame icon and the message

in progress].
• At the end of the second calibration procedure, the display will show the screen relevant to the
parameter
Sc13**

[OK]
.
• The main screen will appear.
The message
[Calibration in progress]
disappears
The flame stops flashing and goes off or remains steady, depending on the boiler status.
* SC12
adjusts the CO
2
simultaneously at max. and min. power. By increasing the parameter va-
lue the CO
2
decreases; by decreasing the parameter value the CO
2
increases.
** SC13
adjusts the CO
2
at minimum power. By increasing the parameter value the CO
2
decrea-
ses; by decreasing the parameter value the CO
2
increases.
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
.
