"Sc" - Combustion Control Parameters Menu
ONLY QUALIFIED PERSONNEL CAN ACCESS THE "SC" MENU AND MODIFY THE RELEVANT PARAMETERS.
Press the Heating buttons to scroll the list of parameters in increasing or decreasing order. Press the DHW buttons to
view or modify the value of a parameter. To save the edited parameter press either the
h”
or
“-”
button (details
3 and 4 - fig. 1).
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 196. 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.
