Priming protection
First Claim
1. A pumping system for at least one aquatic application, the pumping system comprising:
- a pump;
a motor coupled to the pump; and
a controller in communication with the motor,the controller configured to receive a performance value that is indicative of an actual power consumption of the motor,the controller configured to compare the performance value to a reference value indicative of a reference power value of the motor,the controller configured to prime and run the pump when the performance value is less than the reference value and to continue to do so until the performance value is equal to or greater than the reference value.

Abstract
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.

11. A pumping system for at least one aquatic application, the pumping system comprising:
-
a first means for pumping a fluid; a second means for driving the first means; and a third means for controlling the second means, the third means running a program to use a performance value indicative of an actual power consumption of the second means, compare the performance value to a reference value indicative of a priming threshold, and prime and run the first means when the performance value is less than the reference value and to continue to do so until the performance value is greater than the reference value. - View Dependent Claims (12, 13)

14. A pumping system for at least one aquatic application, the pumping system comprising:
-
a pump; a motor coupled to the pump to drive the pump; and a pump controller in communication with the motor, the pump controller including a variable speed drive configured to operate the motor within a range of operation, a user interface, a memory storing a program, and a processor executing the program stored in the memory; wherein the program executed by the processor uses a performance value that is indicative of an actual power consumption of the motor, compares the performance value to a reference value indicative of a dry threshold, and primes and runs the pump when the performance value is greater than the reference value and continues to do so until the performance value is less than the reference value.
