The GARDENA Water Computer MasterControl is attached to the tap and controls the automatic irrigation of your garden, e.g. sprinklers and drip irrigation systems. The programming of the watering times is easy: the operating unit with the large and clear display can be removed for easy programming. The large display explains with on-screen instructions in ten selectable languages which programme steps are to be carried out in which sequence. With the large, easy-to-use rotary knob, the desired data can be quickly revised. Daily, up to six independent programmes or watering intervals with a duration each of one minute to 9 hours 59 minutes can be selected. Additional flexibility: the desired watering days are also freely selectable. In combination with the Automatic Water Distributor by GARDENA, up to six different connecting devices can be individually controlled. For water-saving operation, a GARDENA Rain Sensor or Soil Moisture Sensor can be connected. A purely sensor-controlled irrigation with the Soil Moisture Sensor is also possible. For operation of the GARDENA Water Computer MasterControl, a 9 V alkaline battery is required (not included). This ensures operation for about one year. The integrated battery level display indicates when the battery needs to be changed.
