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： 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 receives input of a performance value that is determined utilizing information from operation of the motor and compares the performance value to a reference value. The controller also is configured to prime and run the pump when the performance value equals the first reference value and to continue to do so until the performance value equals a second reference value. Alternatively, the controller receives user input of an amount of time the system can take to attempt to successfully prime the pump and is configured to operate the motor at maximum speed until the amount of time elapses.

摘要： A pumping system including a pump, a motor coupled to the pump, an automation system, and a pump controller located remotely from the automation system. The pump controller is coupled to at least one pump and the motor, and the pump controller is in digital communication with the motor, the automation system, and at least one auxiliary device. The pump controller transmits data to, and receives data from, the automation system and at least one auxiliary device over at least one communication link and operates the motor based on information entered into the automation system and received from the automation system. The pump controller selectively alters an operation of the motor based on the information received from one of the automation system or parameters received from the at least one auxiliary device. During a lockout state, the pump controller selects one of ignoring, delaying, or rescheduling a water

摘要： Some 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, a user interface associated with the pump designed to receive input instructions from a user, and a controller in communication with the motor. The controller determines a power parameter associated with the motor and compares the power parameter to a predetermined threshold value. The controller triggers a safety vacuum release system based on the comparison of the power parameter and the threshold value.

摘要： A pumping system for at least one aquatic application includes a motor coupled to a pump and a controller in communication with the motor. The controller is adapted to determine a first motor speed of the motor, determine a reference power consumption using a reference flow rate and a curve of speed versus power consumption for the reference flow rate, and generate a difference value between the reference power consumption and a present power consumption. The controller drives the motor to reach a steady state condition at a second motor speed based on the difference value.

摘要： 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.
