GARDENA Water Control Flex
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 instruc-
tions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 auto-
matic 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.
1. 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 com-
puter cools down the LCD display illuminates
again.
The max. temperature for the water flow is 40 °C.
Avoid tensile strain.
vDo 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. There
is also a risk that the polybag can suffocate tod-
dlers. Keep toddlers away when you assemble the
product.

3Select schedule | 4Confirm schedule
Please note: If starting in the past and at a fre-
quency 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 water-
ing cycles are ideal in combination with a drip
irrigation system.
The saved watering schedule can be activated or
deactivated by pressing ON/ OFF.

3Stop 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.

3. FUNCTION v(Fig. F)
The settings can be adjusted when the control
panel is removed. You can change the settings
or move to the next setting by turning the outer

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 sig-
nals that the soil is moist – thereby preventing
watering – is selected via the number of levels.
– 0 dots for loamy soil
v Sensor response when soil is quite dry.
– 3 dots for sandy soil
v 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).
