Abstract
An apparatus and method for controlling plumbing fixtures includes an electronic control board having a microprocessor that accepts four inputs and produces four outputs. Inputs at other than the microprocessor's operating voltage are converted thereto. Outputs having different voltages are controlled by latching relays. The control board can be used with a Smart Sink that requires a sequenced hand washing. The control board can form a node on a network that monitors and controls the functions of multiple boards throughout a facility.
