PARAMETERS "SC12" AND "SC13" MUST BE MODIFIED, IF STRICTLY NECESSARY, BY QUALIFIED PERSON-
NEL AND ONLY WHEN THE CO
2
VALUES ARE OUTSIDE THE RANGE INDICATED IN “- Technical data table”
on page 197. CARRY OUT THE PROCEDURE AFTER AT LEAST 500 HOURS OF BOILER OPERATION.
* SC12
regulates the CO
2
at the same time at maximum and minimum power. By increasing the parameter value the
CO
2
decreases; by decreasing the parameter value the CO
2
increases.
** SC13
regulates the CO
2
at minimum power. By increasing the parameter value the CO
2
decreases; by decreasing
the parameter value the CO
2
increases.
Procedure for modifying parameter SC12:
•
Put the boiler in heating or DHW mode and press the
reset
button (ref. 6 fig. 1) for 10 seconds.
•
The display shows 100 and the text
”Co”
flashing; press the "H" button (ref. 4 fig. 1) to set and view 120.
•
Then press the "DHW +" button (ref. 2 fig. 1) to set 123.
•
Press the
reset
button (ref. 6 fig. 1) once.
•
The display shows
Ts
flashing; press the "h" button (ref. 4 fig. 1) once.
•
The display shows
Sc
flashing; press the
reset
button once.
•
The display shows
Sc
alternating with 01 flashing;
•
Press the "h" button (ref. 4 fig. 1) until displaying
Sc
alternately with 15 flashing;
•
Press the "DHW +" button and the display shows "00";
•
Press the "DHW +" button until the display shows "02";
•
Press the "h" button (ref. 4 fig. 1) to confirm and the 100% calibration mode will activate displaying the mes-
sage “CA” and “LI” alternating.
•
after just over a minute the calibration mode will end and the display will show "C" alternating with "12" with the con-
tinuous flame symbol.
•
press the "DHW +" or "DHW -" button to set the "SC12" parameter value to the value that allows CO
2
optimization.
•
press the "h" button to confirm the value. The display shows "Sc" alternating with "15".
•
Press the Reset button to return to the Service Menu. Press the Reset button for 10 seconds to exit the card Service
Menu, or exiting occurs automatically after 15 minutes
•
put the boiler in TEST mode and check the CO
2
value at maximum and minimum power with an analysis instrument.

•
Press the "h" button (ref. 4 fig. 1) to confirm and the 100% calibration mode will activate displaying the mes-
sage “CA” and “LI” alternating.
•
after just over a minute the calibration mode will end and the display will show "C" alternating with "12" with the con-
tinuous flame symbol.
•
press the "DHW +" or "DHW -" button to set the "SC12" parameter value to the value that allows CO
2
optimisation.
