A burner control ensures that gas and oil burners are safely fired . It ensures complete and controlled combustion of the fuel that has been admitted . To do this, the burner control system primarily monitors the presence of a flame while the burner is in operation. The fresh air supply and the function of the connected sensors are also checked at fixed time intervals.

The technical challenge of a burner control is the intrinsic safety of the device. International standards demand that an automatic burner control - even if a component suddenly becomes defective - must keep the burner in a safe condition, which means, for example, switching off the fuel supply.

In the middle of the 20th century, the machine's program sequence was implemented using a so-called cam switch , consisting of a rotating cam roller or disk and contacts closed by the cams. Electromechanical automatic firing systems, which are complex to produce, have been increasingly replaced by microprocessor-controlled automatic firing systems since the end of the 20th century.
