The GARDENA Water Timer T 1030 plus is attached to the tap and controls the automatic irrigation of your garden, e.g. sprinklers, a drip irrigation system like the Micro-Drip-System, or the GARDENA Sprinklersystem. The programming of the watering times is easy: For convenient programming, the operating unit can be removed. 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. If desired, a GARDENA Rain- or Soil Moisture Sensor can be connected for water-saving operation. For operation of the GARDENA Water Timer T 1030 plus, a 9 V alkaline battery is required (not included). This ensures secure operation for about one year. The integrated battery level display indicates when the battery needs to be changed.
