ABSTRACT:
A method, and a system using the method, of controlling a heating device. The method includes combusting a mixture of fuel and air in a sealed combustion chamber thereby forming a reaction zone in which the fuel reacts with the air, and also forming outside of the reaction zone an ion zone in which ions are formed as a result of combustion. The method also includes positioning an ion detecting member in the ion zone, and generating an electrical signal at the ion detecting member in response to an ion concentration in the ion zone. The method also includes detecting a direction reversal of the electrical signal at the ion detecting member, and stopping combusting the mixture in response to the reverse of the direction of the electrical signal.
