Via GARDENA Controllers, GARDENA Irrigation Valves 9 V (Art. No. 1251-20) are controlled so that these then control the irrigation based on the programmed set times. The GARDENA Controller is programmed through the GARDENA Programming Unit (Art. No. 1241-20), which transfers the data after connection of the valve easily with the press of a button. For operation, one 9 V alkaline battery is required (not included). This ensures secure operation for about one year. If desired, a GARDENA Rain- or Soil Moisture Sensor can be connected for water-saving operation.
