摘要

Automatic control device for electric control applicable in particular to a heating installation powered by liquefied petroleum gas, characterized in that it comprises, assembled in series, one after the other, electrical elements with total or null control that each control a given operating regime of the installation, and control or detection devices that control the choice of operating mode by driving or not driving static switches mounted in parallel each with at least one of said electrical control elements, the electrical resistances of said elements of sufficiently different magnitudes being chosen so that, when an electric current goes through in series several electric control elements mentioned, only, of them, the one with the greatest resistance is powered under a sufficient electrical voltage to ensure its functioning.
