Abstract

Methods and systems of controlling the operation of a pump according to a pump operation schedule are described. In one constructions, a pump controller enters a programming mode and monitors a number of inputs received through a user interface while in the programming mode. The programming mode is then exited and a delay time is defined equal to one hour for each input received through the user interface while in the programming mode. A stored pump operation schedule is accessed and operation of the pump is initiated according to the pump operation schedule after a period of time equal to the delay time has elapsed since exiting the programming mode. Operation of the pump is again initiated according to the accessed pump operation schedule every twenty-four hours since the pump operation schedule was last initiated.

Claims

1. A method of controlling the operation of a pump, the method comprising:

entering a programming mode;

monitoring a number of inputs received through a user interface while in the programming mode;

defining a delay time based on the monitored number of inputs;

accessing a stored pump operation schedule;

initiating operation of the pump according to the accessed pump operation schedule based on the defined delay time;

initiating operation of the pump according to the accessed pump operation schedule after a defined schedule repeat period has elapsed since the pump operation schedule was last initiated;

wherein the act of monitoring a number of inputs received through a user interface while in the programming mode includes monitoring a number of times that a first button is pressed and a number of times that a second button is pressed; and

wherein the act of defining a delay time based on the monitored number of inputs includes adding one hour to the delay time for each time that the first button is pressed and subtracting one hour from the delay time for each time that the second button is pressed.

2. The method of claim 1, wherein the act of defining a delay time based on the monitored number of inputs includes defining the delay time as equal to one hour for each input received through the user interface while in the programming mode.

3. The method of claim 1, wherein the act of initiating operation of the pump according to the accessed pump operation schedule based on the defined delay time includes initiating the operation of the pump according to the accessed pump operation schedule after a period of time equal to the delay time has elapsed since exiting the programming mode.

4. The method of claim 1, wherein the act of initiating operation of the pump according to the accessed pump operation schedule after a defined schedule repeat period has elapsed since the pump operation schedule was last initiated includes initiating operation of the pump according to the accessed pump operation schedule after a period of twenty-four hours has elapsed since the pump operation schedule was last initiated.

5. The method of claim 1, wherein, when the defined delay time is less than zero, the act of initiating operation of the pump according to the accessed pump operation schedule based on the defined delay time includes

adding the defined delay time to the defined schedule repeat period;

and

initiating the operation of the pump according to the accessed pump operation schedule after a period of time equal to a sum of the defined delay time and the defined schedule repeat period has elapsed since exiting the programming mode.

6. The method of claim 1, further comprising monitoring an amount of time that a button of the user interface is held, and wherein the act of entering the programming mode includes entering the programming mode when the button of the user interface has been held for longer than a defined period of time.

7. The method of claim 1, further comprising tracking an amount of time remaining until the pump operation schedule is to be initiated next based on an elapsed amount of time since the pump operation schedule was last initiated, and wherein the act of initiating operation of the pump according to the accessed pump operation schedule based on the defined delay time includes adding one hour to the amount of time remaining until the pump operation schedule is to be initiated next for each input received through a user interface while in the programming mode.

8. A pump controller including a user interface, a processor, and a memory storing instructions that, when executed by the processor, cause the pump controller to:

enter a programming mode;

monitor a number of inputs received through the user interface while in the programming mode;

define a delay time based on the monitored number of inputs;

access a pump operation schedule stored on the memory;

initiate operation of the pump according to the accessed pump operation schedule based on the defined delay time;

initiate operation of the pump according to the accessed pump operation schedule after a defined schedule repeat period has elapsed since the pump operation schedule was last initiated;

wherein the user interface includes a first button and a second button; and

wherein the instructions, when executed by the processor, further cause the pump controller to

monitor a number of inputs received through a user interface while in the programming mode by monitoring a number of times that the first button of the user interface is pressed and the number of times that a second button of the user interface is pressed, and

cause the pump controller to define a delay time based on the monitored number of inputs by adding one hour to the delay time for each time that the first button is pressed and subtracting one hour from the delay time for each time that the second button is pressed.

9. The pump controller of claim 8, wherein the instructions, when executed by the processor, cause the pump controller to define a delay time based on the monitored number of inputs by defining the delay time as equal to one hours for each input received through the user interface while in the programming mode.

10. The pump controller of claim 8, wherein the instructions, when executed by the processor, cause the pump controller to initiate operation of the pump according to the accessed pump operation schedule based on the defined delay time by initiating the operation of the pump according to the accessed pump operation schedule after a period of time equal to the delay time has elapse since exiting the programming mode.

11. The pump controller of claim 8, wherein the instructions, when executed by the processor, cause the pump controller to initiate operation of the pump according to the accessed pump operation schedule after a defined schedule repeat period has elapsed since the pump operation schedule was last initiated by initiating operation of the pump according to the accessed pump operation schedule after a period of twenty-four hours has elapsed since the pump operation schedule was last initiated.

12. The pump controller of claim 8, wherein, when the defined delay time is less than zero, the instructions, when executed by the processor, cause the pump controller to initiate operation of the pump according to the accessed pump operation schedule based on the defined delay time by

adding the defined delay time to the defined schedule repeat period;

and

initiating the operation of the pump according to the accessed pump operation schedule after a period of time equal to a sum of the defined delay time and the defined schedule repeat period has elapsed since exiting the programming mode.

13. The pump controller of claim 8, wherein the instructions, when executed by the processor, further cause the pump controller to monitor an amount of time that a button of the user interface is held, and cause the pump controller to enter the programming mode when the button of the user interface has been held for longer than a defined period of time.

14. The pump controller of claim 8, wherein the instructions, when executed by the processor, further cause the pump controller to track an amount of time remaining until the pump operation schedule is to be initiated next based on an elapsed amount of time since the pump operation schedule was last initiated, and cause the pump controller to initiate operation of the pump according to the accessed pump operation schedule based on the defined delay time by adding one hour to the amount of time remaining until the pump operation schedule is to be initiated next for each input received through a user interface while in the programming mode.
