Product Description


  • Dual outlet water computer
  • The GARDENA MultiControl Duo Water Computer connects to the tap and controls the irrigation of your garden automatically without having to lift a finger. It can be used to set automatic irrigation schedules for two separate garden areas or allows one outlet to be used for programming while keeping the other outlet free for use when required. The rotating swivel Tap Nut Adaptor allows the Water Computer to be connected to a tap that is located very close to a wall
  • Programming is uncomplicated thanks to the step-by-step menu and easy-to-read LCD display. Each program can contain up to three irrigation sessions a day (24, 12 or 8 hour blocks) for up to 3 hours 59 minutes each. The choice of watering days is extremely flexible and simple to set. The watering days can be selected freely (any combination of M-Tu-W-Th-F-Sa-Su) or as specific intervals (every 2nd/3rd/7th day). Comes with 2-year warranty


Automatic and time-saving irrigation

  • With a GARDENA Water Computer, your garden will be reliably and conveniently irrigated – even when you are not home. You win more free time and have a lush, green garden and beautiful, healthy plants. With the automatic irrigation in the early morning hours or evening, less water evaporates. This saves money and allows targeted, optimal irrigation

Top product quality

  • GARDENA German-made quality products stand for trusted performance, reliability and continual innovation

Safe operation

  • The battery level display shows you the charging status of the battery. You will know in time when the battery needs to be changed. This ensures reliable operation of the Water Computer

Convenient irrigation at the press of a button in two garden areas, e.g. lawn and bed

  • What a human can’t do, a Water Computer can: divide itself. With the press of a button, you can water e.g. the lawn in the back yard and the flower boxes in the front yard with varying watering durations and frequencies

Intuitive operation – it doesn’t get any easier

  • The control panel of the Water Computer is easy to detach, the functions are intuitive to operate and the large display shows all data clearly

Water-saving operation

  • With the connection of a GARDENA Rain or Soil Moisture Sensor, the automatic irrigation is interrupted depending on the soil moisture and natural rain. With the GARDENA Soil Moisture Sensor, irrigation can also be controlled solely based on the sensors


  • Energy supply 1 x 9 V alkaline battery (not included)
  • Sensor connection Yes
  • Operating pressure Min 0.5 bar
  • Operating pressure Max 12 bar
  • Thread For taps with 3/4″ and 1″ thread
