A water softener controller for softener plants. Suitable for simplex, duplex and triplex column installations with control valves or pilot valves

ES2070TV water softener controller for softner plants. Suitable for simplex, duplex and triplex column installations with control valves or pilot valves


The ES2070TV water softener(filter) controller is universal applicable for automatic monitoring and control of softener plants and suitable for simplex(single), duplex(double) and triplex(triple) column installations in alternating and parallel circuits. Universally implementable for a wide range of control valves and pilot valves of well known brands like Fleck, Siata, Eurowater and Autotrol. Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into a non volatile memory and therefore not be affected by power loss.
