Abstract:
In combination, a controller, with a localized preexisting circuit, for detecting an initial alternating current flow across a load's open/close switch and for managing subsequent alternating current flow across said load's open/close switch, said combination comprising:a) said localized preexisting circuit coupled with said load's open/close switch: andb) said controller connected to said localized preexisting circuit at a location remote from said load's open/close switch, wherein said controller further comprises:i) a memory coupled to an electro-optical sensor for receiving input from said electro-optical sensor; andii) a sub-combination, including a relay, for receiving management output signals supplied by said memory, wherein said relay manages said subsequent alternating current flow across said load's open/close switch and supplies direct current to said electro-optical sensor.
