"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 store the modified parameter, press the heating"+" button or "-" button
(details 3 and 4 - fig. 1).

Functional description
Allows the change of gas type. See "Gas conversion"
on page 169
Allows the amount of gas to be increased or
decreased in the ignition phase in case of difficult start-
ing.
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. 26.
Allows the minimum power to be increased, if neces-
sary.
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 ionization value reached during
the ignition phase.
Displays the time from fan activation to ionization.
Allows the adjustment of CO
maximum 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 170) when replacing some components (see
"Extraordinary maintenance and replacement of com-
ponents" on page 182)
Allows updating or restoring the circuit board parame-
ters (see "Loading parameters with KEY" on page 171)
