Abstract
A control system comprising a timer based controller and a valve wherein the timer-based controller has a fixed period and the timer based controller regularly cycles the valve between a first condition and a second condition with the first portion of the cycle directing a first flow of water through a dispensable material and the remaining portion of the cycle directing a lesser flow of water through the dispensable material.
Claims25
A system for cyclical control of a water characteristic without feedback comprising:
- a body of water;
- a circulation line to and from the body of water;
- a dispenser located in the circulation line;
- a dispensable material located in the dispenser;
- a pump for directing water into the circulation line;
- a valve having an open condition to allow water to flow through the circulation line and a closed condition to prevent water from flowing through the circulation line;
- and
- a controller, said controller repeatedly generating a signal having a fixed time period with a portion of the fixed time period comprising a valve open signal to open the valve to allow water to flow through the dispenser and a remaining portion of the fixed time period comprising a valve close signal to close the valve to prevent water from flowing through the dispenser to thereby periodically limit the dispensing of the dispensable material into the body of water.
A system for cyclical time control of a water characteristic comprising:
- a dispensable material deliverable to a body of water;
- a valve having a first valve open condition and a second condition;
- and
- a controller repeatedly generating a control signal with a fixed time period with a portion of the fixed time period comprising a valve open signal to allow water to flow through the dispensable material and a remaining portion of the fixed time period comprising a valve close signal to decrease flow through the dispensable material during the remaining portion of the fixed time period.
A cyclical method of controlling a characteristic of a body of water comprising:
- circulating water to and from a body of water through a dispenser;
- selecting a dispensing cycle having a dispensing cycle period;
- selecting a portion of the dispensing cycle period that the dispenser is in an open condition and a remaining portion of the dispensing cycle the dispenser is in a second condition;
- and
- controlling the characteristic of the body of water by continually repeating the dispensing cycle.
