摘要： A pumping system for a pool or spa application that pumps water. The pumping system comprising a means for moving water through the pool or spa application, a means for driving the means for moving water, and a means for controlling the means for driving. The means for controlling monitors a current flow rate based on an input power to the means for driving, monitors whether the current flow rate is above a priming flow value in order to identify whether the means for moving water has become initially primed, and indicates a priming alarm if the means for moving water has not become initially primed before reaching a maximum priming time allotment, wherein the maximum priming time allotment is a fixed time period.

摘要： A pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, a filter coupled to the pump, and a controller in communication with the motor. The controller is configured to make a sensorless determination of a current value of a water flow rate based on an input power to the motor, drive the motor speed to maintain the water flow rate at a first constant value during a first time period, and drive the motor speed to maintain the water flow rate at a second constant value during a second time period.

摘要： 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.
