Flow locking system and method
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 pump controller in communication with the motor,the pump controller including a user interface configured to initially receive and set a maximum locked flow rate, a minimum locked flow rate, a maximum speed, a minimum speed, and a plurality of programmed flow rate settings including a first programmed flow rate setting,the pump controller configured to permanently disable resetting of the maximum locked flow rate and the minimum locked flow rate once they are initially received and set through the user interface while allowing resetting of the maximum speed, the minimum speed, and the plurality of programmed flow rate settings,the pump controller configured to operate the motor in order to maintain a first flow rate through the pumping system set by the first programmed flow rate setting as long as the first flow rate is between the minimum locked flow rate and the maximum locked flow rate.

Abstract
A pumping system and method including a flow locking feature. A pump controller includes a user interface configured to initially receive and set a plurality of programmed flow rate settings, a maximum locked flow rate, and a minimum locked flow rate. The pump controller is also configured to disable resetting of the maximum flow rate and the minimum flow rate once they are initially received and set and to allow resetting of the plurality of programmed flow rate settings throughout operation of the pumping system. The pump controller is further configured to operate a pump motor in order to maintain a first flow rate set by one of the plurality of programmed flow rate settings as long as the first flow rate is between the minimum locked flow rate and the maximum locked flow rate.

16. A method of operating a controller of a pump including a motor for use in a pumping system, the method comprising:
-
receiving from a user interface a maximum flow rate and a minimum flow rate; receiving from the user interface a maximum speed and a minimum speed; receiving from the user interface a first programmed flow rate setting including at least a first flow rate; receiving from the user interface a second programmed flow rate setting including at least a second flow rate; locking the maximum flow rate and the minimum flow rate as permanent parameters of the pumping system such that resetting of the maximum flow rate and the minimum flow rate is permanently disabled once the maximum flow rate and the minimum flow rate are initially received through the user interface and locked; allowing resetting of the maximum speed, the minimum speed, the first programmed flow rate setting, and the second programmed flow rate setting; selecting one of the first flow rate and the second flow rate as a selected flow rate for current pump operation; and operating the motor to maintain the selected flow rate as long as the selected flow rate is between the maximum flow rate and the minimum flow rate. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
