100% calibration
IMPORTANT: DURING THE AUTOMATIC CALIBRATION PROCEDURE AND CHECK OF THE
CO
2
VALUE, THE FRONT CASING OF THE BOILER MUST BE CLOSED AND THE INTAKE/
FUME EXHAUST DUCTS COMPLETELY ASSEMBLED.
100% calibration, automatic
Automatic calibration can take place in some cases in the absence of a DHW or heating demand
or after a reset due to a fault and is indicated on the display by the flashing flame symbol.
100% calibration, manual
With this procedure it is possible to perform an automatic calibration on command, i.e. indepen-
dently from the control board calibration logics and therefore even when the control board does
not consider it strictly necessary
