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.
Claims25
A system for cyclical control of a water characteristic in a body of water with or without feedback comprising:
- a cyclic controller responsive to either a stand alone display or an integrated spa display, said cyclic controller repeatedly generating a cyclic output signal having a first signal and a second signal with the first signal different than the second signal;
- and
- a valve responsive to the first signal and the second signal to periodically deliver a water characteristic affecting material into a body of water in response to the first signal and the second signal to thereby either maintain or change the water characteristic of the body of water.
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;
- and
- controlling the characteristic of the body of water by continually repeating the dispensing cycle to periodically release a water characteristic affecting material.
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.
A system for cyclical control of a water characteristic in a body of water with or without feedback comprising:
- a cyclic controller repeatedly generating a cyclic output signal having a first signal and a second signal with the first signal different than the second signal;
- and
- a valve responsive to the first signal and the second signal to periodically deliver a water characteristic affecting material into a body of water in response to the first signal and the second signal to thereby either maintain or change the water characteristic of the body of water.
