Abstract
A control system for a water treatment apparatus that includes a control valve assembly having a servo chamber in which a stationary port defining signal ports is located. A regeneration control disc sealingly engages and rotates on a planar surface of the port disc and selectively communicates fluid signals to water pressure operated components within the control valve. An electric motor located in a dry chamber is operatively coupled to the regeneration control disc and rotates the disc during a regeneration cycle. An encoder coupled to the control disc monitors its position and movement. A turbine assembly monitors water treated or to be treated and is electronically coupled to a regeneration controller. A sensor emits pulses related to rotation of the usage turbine and communicates these pulses to the controller which uses this information to determine when a regeneration is needed whereupon the drive motor is appropriately energized.
