TUNZE® RO Water Controller 8555 is an automatic water level controller used in the collection container of 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 an 11 V power supply unit. Depending on the use, the water valve can be replaced by switched socket outlet 3150.110 for mains 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 it can also be used for automatic filling or emptying of tanks. By means of a combination of two units, a water changing system can be built.
