Intended use:
The GARDENA Water Control is intended for private use in domestic and hobby gardens, exclusively for outdoor use, to control sprinklers and watering systems. The Water Control has two separate outlets and can be used e. g. for automatic irrigation during your holiday.

DANGER! The GARDENA Water Control must not be used for industrial purposes or in conjunction with chemicals, foodstuffs, easily flammable and explosive materials.

OVERVIEW

SAFETY WARNINGS

IMPORTANT! Read the operator’s manual carefully before use and keep for future reference.

Battery:
To ensure the Water Control runs safely, only a 9 V alkaline manganese battery (alkaline) type IEC 6LR61 must be used. In order to stop the Water Control from failing because of a weak battery if you are away for a long time, the battery must be replaced when the battery display still shows only 1 bar.

Initial Operation:
The Water Control must not be used indoors.

• Only use the Water Control outdoors.

  • The Water Control may only be set up vertically with the sleeve nut to the top to prevent water penetrating into the battery compartment.

  • The minimum water output to ensure correct function-ing of the Water Control is 20 – 30 l/h per outlet.
    E. g. for controlling the Micro-Drip System, at least 10 pieces 2-litre Drip Heads are required.

  • At high temperatures (over 60 °C at the display) the LCD display may extinguish. This does not affect the program in any way. When the Water Control cools down the LCD display illuminates again.

  • The max. temperature for the water flow is 40 °C.

• Only use clear fresh water.

  • The minimum operating pressure is 0.5 bar, the maximum operating pressure is 12 bar.
  • Avoid tensile strain.

• Do not pull the hose connected to the Water Control.

Programming:

• Program the Water Control with the tap turned off. In this way, you can prevent unintentional water penetration.
  • You can remove the control unit from the housing to program the Water Control.
  • If the controller is removed when the valve is open, the valve remains open until the controller is fitted again.

DANGER! Cardiac arrest!
This product makes an electromagnetic field while it operates. This field may under some con-ditions interfere with active or passive medical implants. To decrease the risk of conditions that can possibly injure or kill, we recommend per-sons with medical implants to speak with their physician and the medical implant manufacturer before you operate the product.

DANGER! Risk of suffocation!Small parts can be easily swallowed. There is also a risk that the polybag can suffocate toddlers.

• Keep toddlers away when you assemble the product.

FUNCTION

With the Water Control, the garden can be watered fully automatically up to 3 times a day (every 8 hours) via both outlets. Sprinklers, a sprinkler system or a drip head watering system can be used for watering. The Water Control carries out watering fully auto-matically according to the set program and can therefore also be used during holidays. Early in the morning or late in the evening, evaporation and therefore water consumption is lowest.

Controls [ Fig. F1 ]:
The watering programme is easily entered using the controls.

Display levels:
The 6 display levels can be selected one after the other by pressing the Menu key.

The display level can be changed at any time by pressing the Menu button. All programme data changed up to this time and confirmed with the OK button is saved. If data is changed during programmed irrigation and confirmed with the OK button then the valve is closed.

Display messages [ Fig. F2 ]:

If the battery frame is flashing, the valve is no longer opened. A valve opened by the programme will also close again if the battery is flat.
The battery display is reset when the battery is changed.
