The "Levelcontrol" operating mode is set in the Customer menu of the device controller. This operating mode is used for facilities with
pressure maintaining stations and enables an elastic operation at constant pressure.
Water is added depending on the measured filling level in the expansion tank of the pressure maintaining station. The "LIS“ pressure
pick-up determines the filling level and sends this value to the controller of the pressure maintaining station. The controller sends a 230
V signal to the device controller when the filling level in the expansion tank has fallen below the set value. The device controller
regulates the motor actuator of the 3-ways motor ball valve in the "WC" make-up line. This ensures a controlled make-up with water and
monitoring of the make-up time and cycles.
