Abstract:
1. A control system for a heating system including a combustion chamber, a thermostat, an igniter, an air blower, and a fuel pump, the control system comprising: at least one ultraviolet (UV) sensor configured to be positioned adjacent to a combustion flame source producing a combustion flame in the combustion chamber of the heating system for generating analog signals indicative of the quality of the combustion flame including carbon dioxide content based on the characteristics of UV light generated by the combustion flame; means communicating with the at least one UV sensor for converting the analog signals into digital signals indicative of the quality of the combustion flame including carbon dioxide content based on the characteristics of UV light generated by the combustion flame; means for performing numerical and logical operations on the digital signals, so as to result in data that precisely correlates in a linear fashion with the carbon dioxide content in the combustion gases; and means for tracking changes in the flame quality from an initial setup optimal value, as correlated with the data of the carbon dioxide content of the combustion gases.
