Tunze ^® Ro Water Controller 8555 is an automatic upgrade with regulation for reverse osmosis Tunze ^® RO or all types of opposite osmosis with pure water tank. It consists of a controller, two sensors, a solenoid valve and a 12 V mains supply. To order a device powered on the mains, the solenoid valve can be replaced by the socket ordered 3150.110.
It is also possible to perform a tank controlled drain by simply reversing the position of the Ro water controller sensors and using the controlled socket. By combining two Ro water controller devices, it is possible to have an automated water change installation.
