The classic model GARDENA Water Timer T 1030 with Calendar Function 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 programming of watering times is easily set with a large rotary knob. Daily, up to three watering intervals with a duration each of one minute to 120 minutes can be selected. A GARDENA Soil Moisture sensor or Rain sensor can be connected for water saving operation. Additional flexibility: the desired watering days are also freely selectable (calendar function). For operation of the GARDENA Water Timer T 1030, a 9 V alkaline battery is required (not included). This ensures secure operation for about one year. A weak battery level is indicated.
