Abstract

A method for controlling the operation of a burner, the burner including a control board with a first control unit and a first memory, which stores first values of operating parameters of the burner, and a display device, which displays one or more items of data relating to the functioning of the burner, the display device including a second memory, which stores second values of operating parameters of the burner, each first and second operating parameters being capable of being changed over time. The method includes setting for each operating parameter at least one first value in the first memory, and at least one second value in the second memory; comparing, for each operating parameter, a corresponding first value and second value; if the first value and the second value are different, changing one of the first or second values, so that the first and second values are the same.
