ABSTRACT:
The Electronic Programmable Water Treatment Controller provides an integrated initiator and sequencer for controlling regeneration of water softening and filtering systems. The controller initiates the regeneration sequence or, in the alternative, an alarm based on a programmable prediction time total flow through the water treatment device or combinations of the foregoing. The sequence of regeneration is controlled in response to selected parameters programmable by the user for valve actuation and timing. Multiple water treatment systems may be controlled in alternating, parallel, or progressive control schemes through communication between controllers, attached to each system, which employ the present invention.
