If necessary the default values relating to parameters “S” and “P0 ÷ P2” can be altered by temporarily modifying the type of gas
(parameter “G”) and by restoring it according to the actual operating conditions (wait for approximately 10 seconds between
the gas change and the when it is restored).
The restored values will be those relating to the type of boiler set in parameters “n” and “F”.
At the end of this operation, anomaly “E62” will appear and complete calibration will be required.
Menus “G” - “S” - “n”.
These menus are reserved for air-gas control settings.
Every time these parameters are altered, the complete calibration function must be activated (Par. 3.9).
