"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 heating"+" or "-" button (details
3 and 4 - fig. 1).

Functional description
Allows the change of gas type. See "Gas conversion" on
page 170
Allows the amount of gas to be increased or decreased in
the ignition phase in case of difficult starting.
Allows the fan speed to be increased or decreased in the
ignition phase in case of difficult starting.
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. 27.
Allows the minimum power to be increased, if necessary. 0 ÷ 25
Self-adaptive parameter. DO NOT MODIFY.
Displays the actual ionization current signal.
Displays the actual power referred to maximum power in
DHW.
Displays the maximum ionization value reached.
Displays the minimum ionsation value reached during the
ignition phase.
Displays the time from fan activation to ionization.
Allows the adjustment of CO
mum and minimum power, translating the entire value
curve.
Allows the adjustment of CO
Displays the SCOT system error code.
Allows 100% Calibration (see "100% calibration" on
page 172) when replacing some components (see
