Abstract

An apparatus and method for controlling a water characteristic of a body of water by controlling the cyclic release of a water characteristic material into the body of water with or without the system being responsive to a level of the water characteristic in the body of water with the system capable of being controlled from a display or from a wireless control module or both.

Claims

1-10. -10. (canceled)

11. A cyclical method of day-to-day control of a characteristic of a body of water comprising:

selecting a daily dispensing cycle;

selecting a portion of a daily dispensing cycle period that a dispenser is in a dispensing condition and a remaining portion of the dispensing cycle period the dispenser is in a second condition through a control module either integrated in the system controls or through a control module in wireless communication therewith; and

controlling the characteristic of the body of water by continually repeating the dispensing cycle to periodically release a water characteristic affecting material.

12. The method of claim 11 comprising control of a spa by including the step of directing water through a dispenser containing a water characteristic affecting material when the dispensing cycle period is in the open condition in response to a signal from one of least two control modules wherein at least one of the control modules is a wireless control module.

13. The method of claim 11 including the step of changing the portion of the dispensing cycle period in the open condition and correspondingly changing the remaining portion of dispensing cycle period in the second condition to thereby change an amount of dispensable material deliverable to the body of water over a duty cycle without changing the dispensing cycle period through either of at least two control modules wherein at least one is a wireless control module.

14. The method of claim 11 wherein selecting the dispensing cycle having a dispensing cycle period comprises selecting a spa dispensing cycle having a fixed dispensing cycle period and the step of changing the portion of the dispensing cycle in the open condition and correspondingly changing the remaining portion of cycle in the second condition is done on-the-go by a user.

15. The method of claim 11 the step of further changing a rate of dispensing the water characteristic affecting material from the dispenser by changing the flow through area on a flow area controllable dispenser located in the dispenser through either of at least two spa control modules wherein at least one is a wireless control module.

16. The method of claim 11 including the step of changing a rate of dispensing of the water characteristic affecting material from the dispenser by changing a port size in the dispenser.

17. The method of claim 11 including the step of directing the water from the dispenser through a swimming pool, a spa or hot tub.

18. The method of claim 11 including the step of monitoring a non-water characteristic and temporarily overriding the dispensing cycle to direct more flow through the water characteristic affecting material in response to the non-water characteristic through either of at least two control modules wherein at least one is a wireless control module.

19. The method of claim 18 wherein the step of monitoring a non-water characteristic comprises monitoring an operational time of a jet pump and temporarily overriding the dispensing cycle to direct more flow through the dispensable material in response to the operational time of the jet pump.

20. The method of claim 11 wherein the second condition is a non-dispensing condition.

21. The method of maintaining a water characteristic in a body of water over a period of time comprising:

dispensing a water characteristic affecting material into the body of water; and

regularly interrupting the dispensing of the water characteristic affecting material into the body of water during the period of time to thereby maintain the water characteristic of the body of water by limiting when an amount of the water characteristic affecting material is dispensed into the body of water during the period of time; and

adjusting the dispensing through a control module either proximate or in wireless communication therewith.

22. The method of claim 21 wherein the body of water is in a spa and the period of time is greater than a day.

23. The method of claim 22 including the step of suspending the regularly interrupting the dispensing of the water characteristic affecting material to accommodate extra use of the spa.
