TUNZE ® RO Water Controller 8555 is an automatic water level controller used in the collection container of the TUNZE ® RO station. The controller is also suitable for other water tanks or can be connected to an automatic refill system. It consists of a controller, two sensors, a water valve and a 12 V power supply unit. Depending on the use, the water valve can be replaced with a switched socket outlet 3150.110 for network operation.
If the position of the sensors of the RO water controller is reversed, the switched socket outlet 3150.110 and a pump can be used to empty a water tank, and thus can also be used for automatic filling or emptying of tanks. A water change system can be built by combining two units.
