The comfort model GARDENA Water Timer T 1030 card is attached to the tap and controls the automatic irrigation of your garden, e.g. sprinklers or a drip irrigation system like the Micro-Drip-System. The special feature: it also operates without water pressure, as of an operating pressure of 0 bar, ideal e.g. for rainwater tanks. The programming of the watering times is easy: the desired data is simply set on a programming card with slots. When the card is entered, the data is registered and irrigation is carried out accordingly. Daily, up to three watering intervals with a duration each of one minute to 180 minutes can be selected. After programming, the card can be separately stored, child-safe. 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 card, four 1.5 V alkaline batteries are required (not included). This ensures secure operation for about one year. A weak battery level is indicated.
