Abstract
A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and a filter arrangement in fluid communication with the pump. The pumping system can also include means for determining a load value indicative of an unclogged filter that permits movement of water through the filter arrangement, means for determining a load value indicative of a clogged filter that inhibits movement of water through the filter arrangement, and means for determining a performance value of the pumping system. The pumping system also includes means for determining a relative loading value of the filter arrangement, means for displaying the relative loading value, and means for controlling the motor in response to the relative loading value. In one example, the load values and performance value can include flow pressure values. A method of moving water of a swimming pool is also disclosed.
