The CC3020 conductivity controller designed for full automatic monitoring of the conductivity and eventually starting a regeneration through an external device. The controller is equipped with a conductivity meter and adaptable to user specific requirements by built-in programmable options. Two modes are available inside the controller. From this, a choice can be made as to which programme should be launched by the controller. The base values which are programmed into the controller can be changed at any time and the programmed configuration will be stored into a non volatile memory and therefore not be affected by power loss.
