摘要： A pumping system for moving water of a swimming pool includes a water pump, an infinitely variable speed motor, and an arrangement for operating the motor. In one example, the pumping system includes a memory configured to store a plurality of retained speed values, an arrangement for providing a plurality of retained speed values to the memory, and an arrangement for reading a selected one of the plurality of retained speed values from the memory. In addition or alternatively, the pumping system includes a storage medium for digitally storing a plurality of pre-established motor speed values and an arrangement for receiving input from a user to select one of the pre-established motor speeds. In addition or alternatively, the pumping system further includes an arrangement for restarting operation of the motor at a previously selected speed value when power supplied to the motor is interrupted during operation of the motor. A method for controlling the pumping system is also provided.

摘要： A pumping system includes a water pump for moving water. The pumping system includes means for determining a value indicative of a blockage that inhibits the movement of water through the pumping system, and means for determining a performance value of the pumping system. In one example, the pumping system includes means for comparing the performance value to the value indicative of a blockage and means for controlling the pump in response to the comparison. In another example, the system includes means for determining a change in power consumption of the water pump. In another example, the system includes means for determining a threshold value and means for controlling the pump when the performance value exceeds the threshold value. In another example, the system includes means for determining a difference value based upon a plurality of performance valves during a first time period and a second time period.
