The GARDENA Water Timer T 1030 Duo plus is a complete set to which two Water Timers T 1030 plus can be connected to the tap via a GARDENA Twin-Tap Connector. These can control the automatic irrigation of two accessories or systems, e.g. a sprinkler and a GARDENA Micro-Drip-System. The programming of the watering times is easy: the operating units can be each removed for easier programming. The desired data can be easily set using two large, easy-to-use rotary knobs. Daily, up to three watering intervals with a duration each of one minute to 120 minutes can be selected per Water Timer. If desired, a GARDENA Rain- or Soil Moisture Sensor can be connected for water-saving operation. For operation of each GARDENA Water Timer T 1030 plus, a 9 V alkaline battery is required (not included). This ensures secure operation of one Water Timer for about one year. The integrated battery level display indicates when the battery needs to be changed.
