ABSTRACT:
This invention relates to a control system for regeneration of a water treatment system in which a water meter monitors water usage and mechanically drives a water volume wheel to an operative position to call for regeneration when a predetermined volume of water has been treated and then automatically resets itself. A timer wheel driven by a motor is included within the control system such that the timer wheel and the water volume wheel coact to activate the regeneration cycle mechanism at a predetermined time after a predetermined volume of water has passed through the water meter. The mechanism is adjustable relative to the water treating capacity of the treatment system and the condition of the water being treated so as to be able to vary the predetermined volume of water treated which will call for regeneration.
