Translation of the original instructions.
For safety reasons, children and young people under 16 as well as anyone who is not familiar with these operating instructions should not use the product. Persons with reduced physical or mental abilities may use the product only if they are supervised or instructed by a responsible person. Children must be supervised to ensure that they do not play with the product. Never operate the product when you are tired, ill or under the influence of alcohol, drugs or medicine.

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 can be used for automatic watering during holidays.

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

SAFETY

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

Battery:
To ensure the Water Control runs safely, only a 9V 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 symbol flashes.

Setting up:
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 that the Water Control functions correctly is 20 – 30 l/h. For example, at least 10 x 2-litre Drip Heads are required to control the Micro-Drip-System. At high temperatures (over 70 °C at the display) the LCD display may extinguish. This does not affect the program in any way. When the computer cools down the LCD display illuminates again. The max. temperature for the water flow is 40 °C. Avoid tensile strain.

Do not pull the hose connected to the Water Control.
CAUTION! If the control section is removed when the valve is open, the valve remains open until the control section is reattached.
DANGER! Cardiac arrest!
This product makes an electromagnetic field while it operates. This field may under some conditions interfere with active or passive medical implants. To decrease the risk of conditions that can possibly injure or kill, we recommend persons 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. Ther is also a risk that the polybag can suffocate toddlers. Keep toddlers away when you assemble the product.

A video of the commissioning and setting processes is available here:

PROGRAMMING v (Fig. G – I)

Fig. G: 1 Set time (hours) | 2 Set time (mins) | 3 Select schedule | 4 Confirm schedule Please note: If starting in the past and at a frequency of 4, 6, 8, 12 hours, the start time will be automatically adjusted after input.

Watering tip: For pot plants that required small amounts of water at regular intervals, short watering cycles are ideal in combination with a drip irrigation system. The saved watering schedule can be activated or deactivated by pressing ON / OFF.

Fig. I: 1 Active watering | 2 Change watering duration | 3 Stop active watering at any time By pressing the button, manual watering can be started or stopped at a desired time (see fig. I ). Soil Moisture Sensor v (Fig. D and H): After a soil moisture sensor is connected, the word “Sensor” will be displayed – this can take up to 1 minute. Once the soil is sufficiently moist, a watering operation is interrupted or a schedule is disabled so that it cannot be activated. This does not affect active (manual) watering.

This is the soil moisture level at or above which watering is not to be carried out (see GARDENA Soil Moisture Sensor Operating Instructions). There are 3 levels to choose from.

During normal operation, the currently measured level is displayed constantly.
The switching point as of which the sensor signals that the soil is moist – thereby preventing watering – is selected via the number of levels.
0 dots for loamy soil
Sensor response when soil is quite dry.
3 dots for sandy soil
Sensor response when soil is very moist.

Soil Moisture Sensor, Art. 1188, ( optionally available, models up to 2020) The soil moisture level at which a watering will not be carried out as per the schedule can be set using the switching point controller on the soil moisture sensor (see GARDENA Soil Moisture Sensor Operator’s manual).
