ABSTRACT:
A remote control wiring system is provided with a transformer that supplies a low voltage signal to a low voltage sub-system. The sub-system includes a diode circuit comprising four diodes which permit energization of a first set of relays on a positive portion of a sinusoidal signal and of a second set of relays on the negative portion of the signal. A pair of triacs are provided that move the relays of both sets either in a first direction to open their higher voltage load circuits or in a second direction to close their load circuits. Previous wiring systems did not include the 4-diode circuit and were limited in capacity to control only a single gang of relays. By virtue of the improved system the capacity of the system is reliably doubled, by utilizing the whole of the low voltage control signal.
