Publication number: 20120020810Abstract: Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller determines an actual power consumption of the motor and compares the actual power consumption to a reference power consumption. The controller also determines that the pump is in an unprimed condition if the actual power consumption is less than the reference power consumption and that the pump is in a primed condition if the actual power consumption is at least equal to the reference power consumption.Type: ApplicationFiled: August 29, 2011Publication date: January 26, 2012Inventors: Robert W. Stiles, JR., Lars Hoffmann Berthelsen, Gert Kjaer, Florin Lungeanu

Patent number: 8043070Abstract: 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: GrantFiled: December 11, 2006Date of Patent: October 25, 2011Assignees: Pentair Water Pool and Spa, Inc., Danfoss Low Power Drives, a Division of DanfossInventors: Robert W.

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. Stiles, JR., Lars Hoffmann Berthelsen, Ronald B. Robol, Christopher R. Yahnker, Daniel J. Hruby, Kevin Murphy, Edward Brown, David MacCallum, Dennis Dunn, Kenneth N.
