Abstract
A water treatment system includes a water treatment tank containing a resin bed through which water is passed for treatment thereof during normal operation of the treatment system. A brine tank contains a brine solution which, when passed through the resin bed, results in regeneration of the treatment effectiveness of the bed. A plurality of electrically actuatable valve means direct water through the treatment tank during normal operation of the treatment system and direct brine solution through the treatment tank in a regeneration operation. A control for the water treatment system includes means for manually entering control data, display means for displaying data, and sensor means for sensing the volume of water treated by the water treatment system. A controller circuit means is responsive to means for manually entering control data and to the sensor means and is connected to display data on the display means. The controller circuit means provides electrical control signals to the plurality of electrically actuatable valve means. The sequence, duration, and time of occurrence of the electrical control signals is determined by the control data entered through the means for manu…
