Tunze Controller, (8555.100)
It consists of a controller, two sensors, a water valve and an 11 V power supply unit. Depending on the demand, the water valve can be replaced by switched socket outlet 3150.11 for mains operation.
If the position of the sensors of the RO water controller is reversed, the switched socket outlet 3150.11 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.
