"Sc" - Combustion Control Parameters Menu
ONLY FERROLI TRAINER & QUALIFIED PERSONNEL CAN ACCESS THE "SC" MENU TO MODIFY THE RELE-
VANT PARAMETERS.
Press the Heating buttons to scroll the list of parameters “+“ increasing “-“ decreasing order. Press the DHW buttons to
view or modify the value of a parameter. To save the edited parameter press either the heating“+” or “-” button (details
3 and 4 - fig. 1).
PARAMETERS "SC12" AND "SC13" MUST ONLY BE MODIFIED, IF STRICTLY NECESSARY, BY QUALIFIED
PERSONNEL AND ONLY WHEN THE CO
2
VALUES ARE OUTSIDE THE RANGE INDICATED IN “- Technical data
table” on page 47. 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
reduces; 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
reduces; by decreasing the
parameter value the CO
2
increases.
Contents Description Functional description Range Default
Sc01 Gas type selection
Allows the change of gas type. See “Gas conversion” on
page 21
na / LP na
Sc02 Ignition gas calibration
Allows the amount of gas to be increased or decreased in the
ignition phase (Due to poor ignition).
-9 ÷ 20 0
Sc03 Ignition power
Allows the fan speed to be increased or decreased in the igni-
tion phase in case of poor ignition.
