The ES2030SV water softener controller is universal applicable for automatic monitoring and control of softener or filtering plants(through solenoid valves) and suitable for single and double column installations in alternating, parallel or serial circuits. Adaptable to user specific requirements by built-in programmable options. The software's flexible programming capacity and the individually adaptable hardware make a wide range of uses in water treatment systems possible. In combination with individual valves, this controller can operate ion exchanger systems and filter systems. For single filter systems, 6(or 8, if the IF2030 card is fitted) relays are available for controlling individual valves or for controlling pilot valves or control motors of a multifunction valve. Since only 6(or 8) relays in total are available for dual filter systems too, individual valve systems can only be operated as simple backwashing filters.
