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. 151) .
Contents Description Functional description Range Default
Sc01 Gas type selection Allows the change of gas type. See “Gas conversion” on page 67 na / LP na
Sc02 Ignition gas calibration Allows the amount of gas to be increased or decreased in the ignition phase in
case of difficult starting.
-9 ÷ 20 0
Sc03 Ignition power Allows the fan speed to be increased or decreased in the ignition phase in case
of difficult starting.
-16 ÷ 14 0
Sc04 Flue length Allows the boiler to be arranged according to the width and length of the flue
used. To be used only with Ø50 or Ø60 flues. See fig. 31.
-2 ÷ 13 0
Sc05 Minimum power calibration Allows the minimum power to be increased, if necessary. 0 ÷ 25 0
Sc06 Minimum gas valve calibration Self-adaptive parameter. DO NOT MODIFY.
Sc07 Flame ionization signal Displays the actual ionization current signal. Read only
Sc08 Current power ref. DHW Displays the actual power referred to maximum power in DHW. Read only
Sc09 MAX ionization value Displays the maximum ionization value reached. Read only
Sc10 Minimum ionization value du-
ring ignition
Displays the minimum ionsation value reached during the ignition phase. Read only
Sc11 Ignition time Displays the time from fan activation to ionization. Read only
Sc12* Ionization reduction value
(BASE)
Allows the adjustment of CO2 at the same time as maximum and minimum
power, translating the entire value curve.
-5 ÷ 10 0
Sc13** Ionization reduction value
(min.)
Allows the adjustment of CO2 at minimum power. -5 ÷ 10 0
Sc14 Internal error K1 Displays the SCOT system error code. Read only
Sc15 100% CALIBRATION Allows 100% Calibration (see “100% calibration” on page 68) when replacing
some components (see “15.9 Boiler - Extraordinary maintenance and replace-
ment of components” on page 92)
0 - CAL 0
Sc16 DO NOT MODIFY.
PARAMETERS “SC12” AND “SC13” MUST BE MODIFIED, IF STRICTLY NECESSARY, BY QUALIFIED PERSONNEL AND ONLY WHEN THE CO2 VALUES
ARE OUTSIDE THE RANGE INDICATED IN “Table. 1 - Boiler technical data” on page 9. 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. 151) for 10 seconds.
• The display shows 100 and the text ”Co” flashing; press the “H” button (ref. 4 fig. 151) to set and view 120.
• Then press the “DHW +” button (ref. 2 fig. 151) to set 123.
• Press the reset button (ref. 6 fig. 151) once.
• The display shows Ts flashing; press the “h” button (ref. 4 fig. 151) 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. 151) 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. 151) to confirm and the 100% calibration mode will activate displaying the message “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 continuous flame symbol.
• press the “DHW +” or “DHW -” button to set the “SC12” parameter value to the value that allows CO2 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 CO2 value at maximum and minimum power with an analysis instrument.
