Abstract
A method of operating a variable speed pumping system. The method includes measuring a first power consumption value of a pool pump at a first speed, estimating a first total dynamic head value at the first speed, measuring a second power consumption value of the pool pump at a second speed, estimating a second total dynamic head value at the second speed, and generating a system friction curve based on the first total dynamic head value and the second total dynamic head value. The method also includes categorizing the variable speed pumping system into a pumping system category based on the system friction curve and recommending a modification to the variable speed pumping system based on the pumping category.
