Publication number: 20170198697Abstract: A pumping system for a pool or spa application that pumps water. The pumping system comprising a means for moving water through the pool or spa application, a means for driving the means for moving water, and a means for controlling the means for driving. The means for controlling monitors a current flow rate based on an input power to the means for driving, monitors whether the current flow rate is above a priming flow value in order to identify whether the means for moving water has become initially primed, and indicates a priming alarm if the means for moving water has not become initially primed before reaching a maximum priming time allotment, wherein the maximum priming time allotment is a fixed time period.Type: ApplicationFiled: March 27, 2017Publication date: July 13, 2017Inventors: Robert W.
