What Does A Control Box Do?

The burner control box determines the burners operation by selecting different pre-determined processes. These processes take place utilising camshaft-operated micro-switches on older style control boxes. More recent boxes are controlled digitally using solid state relays. 

Most control boxes are used in conjunction with an array of gas or air pressure switches and a selection of valves. The control box will also take a signal from a flame detection device such as an ionisation rod or a UV Cell.
