Patent ID: 7874808

Claim:
A pumping system for at least one aquatic application including a pool, the pumping system controlled by a user, the pumping system adapted to be coupled to a pool filter and a pool vacuum, the pumping system comprising: a pump; a variable speed motor coupled to the pump; a user interface that receives an input including a desired filtering level of operation from the user including a mode for operation of the pump at an increased level during use of the pool vacuum; and a controller in electrical communication with the variable speed motor and the user interface, the controller determining a current value of at least one of a volume, a flow rate, a mass, and a pressure in the pumping system associated with the desired filtering level of operation, the controller substantially continuously modifying an actual speed of the variable speed motor based on the current value in order to operate the variable speed motor at a substantially minimum speed to achieve the desired filtering level of operation with substantially minimal energy usage; a subsequent aquatic application being added to the pumping system and wherein the controller self-adjusts the actual speed of the variable speed motor to operate at a new minimum speed to achieve the desired filtering level of operation with substantially minimal energy usage.
