Abstract: An electronic control board for supplying control signals including an activation signal to a controlled device in response to a detection signal created by a sensor comprises an on delay timer, a run timer, and an off delay timer. The on delay timer must time out before an activation signal is sent to the controlled device. The run timer permits activation of the controlled device during a run time interval. The off delay timer must time out before a subsequent detection signal will be permitted to generate an activation signal. A lockout timer prohibits generation of an activation signal if the number of activations exceeds a cycle limit. The control board further provides for shutting off the controlled device if the second detection signal occurs during the run time interval.

Abstract: An apparatus for controlling and monitoring the usage of water from plumbing fixtures includes an electronic control board for supplying control signals including an activation signal to a controlled device in response to a detection signal created by a sensor. The electronic control board comprises an on delay timer that must time out before an activation signal is sent to the controlled device, a run timer which permits activation of the controlled device during a run time interval, and an off delay timer that must time out before a subsequent detection signal will be permitted to generate an activation signal. A lockout timer prohibits generation of an activation signal if the number of activations exceeds a cycle limit. The control board further comprises means for shutting off the controlled device if the second detection signal occurs during the run time interval.

Abstract: A plumbing control system includes a plurality of plumbing fixtures operated by an electronic control board having a microprocessor. The control board can form a node on a network that monitors and controls the functions of multiple boards throughout a facility from a central computer. Network software running on the central computer communicates with the control boards. The software includes a binding feature that requires reporting of a network operating variable at a first control board to the central computer or a second control board. The network software also has site and device setup forms.

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.
