Publication number: 20140027359Abstract: 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.Type: ApplicationFiled: July 9, 2013Publication date: January 30, 2014Applicants: Danfoss Low Power Drives, Pentair Water Pool and Spa, Inc.Inventors: Robert W. Stiles, JR., Lars Hoffmann Berthelsen, Ronald B. Robol, Gert Kjaer, Einar Kjartan Runarsson

Publication number: 20130251542Abstract: 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.Type: ApplicationFiled: May 30, 2013Publication date: September 26, 2013Inventors: Robert W. Stiles, JR., Lars Hoffmann Berthelsen, Ronald B. Robol, Christopher Yahnker, Daniel J. Hruby, Kevin Murphy, Einar Kjartan Runarsson, Arne Fink Hansen, Florin Lungeanu, Peter Westermann-Rasmussen

Patent number: 8500413Abstract: The present invention provides a pumping system for moving water of a swimming pool, including a water pump and a variable speed motor. In one example, a target volume amount of water and an operational time period is provided, and the operational time period is altered based upon a volume of water moved. In another example, operation of the motor is altered based upon the volume of water moved. In addition or alternatively, a target flow rate of water to be moved by the water pump is determined based upon the target volume amount and a time period. In addition or alternatively, a plurality of operations are performed on the water, and a total volume of water moved by the pump is determined. In addition or alternatively, an optimized flow rate value is determined based upon power consumption.Type: GrantFiled: March 29, 2010Date of Patent: August 6, 2013Assignees: Pentair Water Pool and Spa, Inc., Danfoss Low Power Drives A/SInventors: Robert W.

Patent number: 8465262Abstract: Embodiments of the invention provide a pumping system for at least one aquatic application controlled by a user. The pumping system includes a pump, a variable speed motor, a memory, and a controller. The pumping system includes a user interface with a first speed button, a second speed button, an increase button, and a decrease button. The buttons provide an actuate and release operation, a first touch and hold operation, and a second touch and hold operation. The controller operates the variable speed motor at a substantially constant speed based on a current speed value selected by the user using the buttons.Type: GrantFiled: October 24, 2011Date of Patent: June 18, 2013Assignee: Pentair Water Pool and Spa, Inc.Inventors: Robert W. Stiles, Jr., Lars Hoffmann Berthelsen, Ronald B. Robol, Christopher R. Yahnker, Daniel J. Hruby, Kevin Murphy, Einar Kjartan Runarsson, Arne Fink Hansen, Florin Lungeanu, Peter Westermann-Rasmussen

Patent number: 8019479Abstract: A pumping system includes a pump for moving water. In one aspect, this is in connection with performance of an operation. The system includes a variable speed motor operatively connected to drive the pump. A value indicative of flow rate of water is determined and the motor is controlled to adjust the flow rate indicative value toward a constant. A value indicative of flow pressure is determined and the motor is controlled to adjust the flow pressure indicative value toward a constant. A selection is made between flow rate control and flow pressure control. In another aspect, the pump is controlled to perform a first operation, and is operated to perform a second water operation. Control of operation of the pump to perform the first water operation is altered in response to operation of the pump to perform the second operation.Type: GrantFiled: November 23, 2005Date of Patent: September 13, 2011Assignee: Pentair Water Pool and Spa, Inc.Inventors: Robert W.

Publication number: 20110091329Abstract: A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and an arrangement for controlling the variable speed motor. The pumping system further includes an auxiliary device operably connected to the arrangement for controlling, and an arrangement for providing two-way communication between the arrangement for controlling and the auxiliary device. The arrangement for controlling is capable of receiving a parameter from the auxiliary device through the arrangement for providing two-way communication. In one example, the arrangement for controlling is capable of independently controlling the variable speed motor without receipt of a parameter from the auxiliary device. In addition or alternatively, the arrangement for controlling is operable to selectively alter operation of the motor based upon the parameter.Type: ApplicationFiled: December 20, 2010Publication date: April 21, 2011Inventors: Robert W.
