Functional description
Allows the change of gas type. See "Gas conversion" on
page 166
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. 25.
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 ionization 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 167) when replacing some components (see
"Extraordinary maintenance and replacement of compo-
nents" on page 179)
Allows updating or restoring the circuit board parameters
