CONTROL BOARD FOR CONTROLLING AND MONITORING USAGE OF WATER

摘要

An apparatus and method for controlling plumbing fixtures includes an electronic control board having a microprocessor that accepts four inputs an d 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.
