Abstract

Systems and methods for combined controlling chlorinators and pumps for pools and spas are provided. Exemplary embodiments can include a pump operable to circulate a fluid for a specified time period according to a pump operation time setting and a chlorinator operatively coupled to the pump. The chlorinator can be configured to generate chlorine based on a chlorine output setting, a chlorine generation capacity of the chlorinator, and the pump operation time. A controller can be operatively coupled to the chlorinator and the pump and can be programmed to control the chlorinator and the pump based on a relationship between the chlorine output setting, a chlorine generation capacity of the chlorinator, and the pump operation time.

First claim

What is claimed is:

1. A system for controlling chlorine output of a chlorinator and a circulation schedule of a pump, the system comprising:
a pump operable to circulate a fluid according to a pump operation time setting;
a chlorinator operatively coupled to the pump and through which the fluid is circulated by the pump; and
a controller operatively coupled to the chlorinator and the pump, the controller accepting settings from a user for the pump operation time setting and a chlorine output setting, the controller being programmed to automatically control the chlorinator and the pump based on a relationship between the chlorine output setting, a chlorine generation capacity of the chlorinator, and the pump operation time setting.

2. The system of claim 1 , wherein the controller is programmed to automatically control a chlorine feed rate of the chlorinator or the pump operation time setting to achieve the chlorine output.

3. The system of claim 2 , wherein the controller receives an input from the user increasing the chlorine output setting and the controller is programmed to determine whether to increase the chlorine feed rate or the pump operation time setting to achieve the chlorine output setting.

4. The system of claim 3 , wherein the chlorine feed rate is set to a maximum value and the controller increases the pump operation time setting.

5. The system of claim 2 , wherein the controller increases the chlorine feed rate and maintains the pump operation time setting.

6. The system of claim 2 , wherein the controller receives an input from the user decreasing the chlorine output setting and the controller is programmed to decrease the chlorine feed rate while the pump operation time is unchanged.

7. The system of claim 2 , wherein the controller receives an input from the user decreasing pump operation time and the controller is programmed to determine whether the chlorine feed rate is adjustable to maintain the chlorine output setting.

8. The system of claim 7 , wherein the controller decreases the chlorine output setting in response to a determination that the chlorine feed rate is not adjustable to maintain the chlorine output setting.

9. The system of claim 7 , wherein the controller increases the chlorine feed rate in response to a determination that the chlorine feed rate is adjustable to maintain the chlorine output setting and the controller maintains the chlorine output setting.

10. The system of claim 8 , further comprising:
a control panel having a display configured to provide a visual indication of the chlorine output setting,
wherein the controller is programmed to interact with the display to change the visual indication based on the decrease of the chlorine output setting.

11. The system of claim 1 , wherein the controller controls an operation of the pump indirectly via another controller.

12. A method of controlling a chlorine feed rate of a chlorinator and operation time of a pump operatively coupled to the chlorinator, the method comprising:
receiving an input from a user via a control panel associated with a controller operatively coupled to a chlorinator and a pump, the chlorinator having a configurable chlorine output setting, the pump having a configurable pump operation time setting; and
controlling a chlorine feed rate and the pump based on a relationship between the chlorine output setting, a chlorine generation capacity of the chlorinator, and the pump operation time setting.

13. The method of claim 12 , wherein receiving the input from the user comprises receiving an increase to the chlorine output setting and the method further comprises determining whether to increase the chlorine feed rate or the pump operation time setting to achieve the chlorine output setting.

14. The method of claim 13 , wherein it is determined the chlorinator is unable to increase the chlorine feed rate to maintain the chlorine output setting and the method comprises increasing the pump operation time setting.

15. The method of claim 13 , further comprising increasing the chlorine feed rate
and maintaining the pump operation time setting.

16. The method of claim 12 , wherein receiving the input from the user comprises receiving a decrease to the chlorine output setting and the method further comprises determining whether to decrease the chlorine feed rate or the pump operation time setting to achieve the chlorine output setting.

17. The method of claim 16 , further comprising decreasing the chlorine feed rate and maintaining the pump operation time setting.

18. The method of claim 16 , further comprising decreasing the pump operation time setting and maintaining the chlorine feed rate.

19. The method of claim 16 , further comprising decreasing the pump operation time setting and decreasing the chlorine feed rate.

20. The method of claim 12 , wherein receiving the input from the user comprises receiving a decrease to the pump operation time setting and the method further comprises determining whether the chlorine feed rate is adjustable to maintain the chlorine output setting.

21. The method of claim 20 , further comprising:
increasing the chlorine feed rate in response to a determination that the chlorine feed rate is adjustable to maintain the chlorine output setting; and
maintaining the chlorine output setting.

22. The method of claim 20 , further comprising:
determining that the chlorine feed rate is not capable of being adjusted to maintain the chlorine output setting; and
decreasing the chlorine output setting.

23. The method of claim 22 , further comprising:
changing a visual indication on a display of the control panel based on a decrease of the chlorine output setting.

24. The method of claim 12 , wherein controlling the chlorinator and the pump comprises executing code by the controller that is operably coupled to the chlorinator and the pump to implement a control process, wherein the controller controls an operation of the pump indirectly via another controller.

25. A method of determining a chlorine feed rate of a chlorinator and a schedule of operation for a pump operatively coupled to the chlorinator, the method comprising:
receiving an input from a user to adjust a chlorine output setting via a control panel associated with a controller operatively coupled to a chlorinator and a pump, the chlorinator having a configurable chlorine feed rate setting, the pump having a configurable pump operation time setting;
determining at least one of the chlorine feed rate setting or the pump operation time setting to be set to achieve the chlorine output setting; and
indicating to the user that an adjustment of at least one of a chlorine feed rate or the pump operation time setting is required to achieve the chlorine output setting.

26. The method of claim 25 , wherein indicating to the user that an adjustment of at least one of the chlorine feed rate or the pump operation time setting is required to achieve the chlorine output setting comprises prompting the user via the control panel to increase at least one the chlorine feed rate or the pump operation time setting in response to receiving an input to increase the chlorine output setting.

27. The method of claim 25 , wherein indicating to the user that an adjustment of at least one of the chlorine feed rate or the pump operation time setting is required to achieve the chlorine output setting compris
