Abstract
A water delivery system includes a water input port, a control circuit, and a valve device. The water input port is constructed to be coupled to a water conduit receiving water from a remotely located water source. The valve device includes an actuator located near and connected to the water input port; wherein the valve device is constructed to receive control signals from the controller for providing water to a water delivery unit. The controller may be battery operated. The actuator may be a latching actuator, a non-latching actuator, or an isolated latching actuator. The controller may include a microcontroller coupled and to a sensor. The system may include a communication interface constructed and arranged to provide data to the microcontroller. The control circuit may include a power consumption controller. The control circuit includes a voltage regulator.
