Abstract
A control unit for operating a valve system in a water conditioner system includes a drive motor having an output shaft coupled to the valve system, a valve position slide switch, an electronic regeneration controller, and a settable mechanical clock. The electronic controller can be programmed by the use of electrical jumpers/dip switches/control knobs. As the drive motor drives the output shaft coupled to the valve system, the drive motor also contemporaneously rotates a dual lead screw in the valve position slide switch. The dual lead screw drives an electrical contactor along a series of electrical contacts in a closed loop fashion. Each of the discrete electrical contacts corresponds to a position of the valve. The electronic controller controls the position of the valve in accordance with dwell times programmed into the electronic controller. If a demand regeneration scheme is desirable, a hardness setting rotary potentiometer can be used to provide analog electrical control.
