Abstract: An energy saving, optoelectronic system provides a means for energizing and deenergizing electrical loads. The system includes a continuous light transmission source and a light receiving circuit that senses a light pattern and, in response, develops a first or a second output signal. The system also includes a gating circuit that receives the output signal. The gating circuit comprises a logic circuit arranged such that the receiving circuit will transmit the second output signal upon receiving a predetermined light signal. The system further includes a power switch that is open in response to an open circuit signal from the gating circuit and is closed in response to close circuit signal from the gating circuit. This system further includes a timing circuit for periodically energizing and deenergizing heating, ventilating, and air-conditioning loads.
