CONTROL DEVICE FOR A BURNER AND ADJUSTING METHOD

The invention relates to a control system (15) for a burner and a setting-up procedure. The control system (15) controls the air ratio for combustion using the ionisation electrode (16). For calibration, a change is carried out in a first parameter, and the subsequent change in a second parameter is observed. Accurate expected values for the change observed come from stored characteristic data that have been determined in the setting-up procedure, and from taking into account the current combustive content of air and fuel. This allows corrective measures or fault signals to be established.
