Viessmann 7816460 Cad Cell 321894-708 Avoid areas with high turbulenceThe Viessmann 7816460 Cad Cell is a critical flame sensor designed for precise oil burner monitoring in residential and commercial heating systems. As a high performance cadmium sulfide photocell, this component acts as a vital safety interface, sensing light in the visible spectrum to verify ignition and continuous combustion. When the burner fires, the Viessmann cad cell resistance should typically drop below 1,600 ohmsoften settling between 300 and
