5.1 Choosing the Installation
Position
The Soil Moisture Sensor must
be positioned in the area which is
watered with the same climatic
conditions (sun, wind, rain etc.)
as the plants. The Soil Moisture
Sensor must not be covered
by neighbouring plants. Avoid
shaded areas. To prevent the
moisture sensor reacting incor-
rectly due to water logging, it
must not be placed in dips in
the ground.
When using the GARDENA
micro-drip system, a 4.6 mm
(3 /16
”
) supply pipe with drip
head must be installed on the
driphead holder
8
of the soil
moisture sensor. The water from
this drip head is measured by
the ceramic sensor
7
.
5.2 Setting-up and Filling
the Sensor
Note :
To prevent the Soil Mois-
ture Sensor reacting incorrectly
after installation, it should only be
installed in dry weather and when
the soil is dry.
1. After you have chosen a suit-
able position, you must prepare
the soil ready to install the
Soil Moisture Sensor. Loosen
an area of soil approx. 10 cm
across and 10 cm deep.
Remove any stones to prevent
damaging or breaking the
sensitive ceramic sensor
7
.
2. Before pushing the GARDENA
Soil Moisture Sensor into the
ground, fill the water container
6
with water. To do this, un-
screw the lid with the low-
pressure controller
5
and
fill the water container
6
with
clean water
to where the
thread begins.
3. Replace the lid
5
on the water
container
6
and
slowly screw
tight until the stop.
Note : When closing the Soil
Moisture Sensor, ensure that
the thread and sealing ring
are free from particles of dirt.
4. Push the Soil Moisture Sensor,
filled with water approx. 10 cm
into the ground (Fig. C).
Push
the soil down around the Soil
Moisture Sensor and water
(the ceramic tip must not be
exposed to the air after in-
stallation).
5. Connect the soil moisture
sensor to the GARDENA water
controller with the supplied
cable
1
.
Important :
The cable must be
laid such that it cannot be dam-
aged or tripped over. When laying
the cable underground, we rec-
ommend using a bed of sand.
Warning :
The Soil Moisture
Sensor must be fixed firmly in the
ground. Therefore, after plugging
the cable into the water controller
and setting the moisture level
(see point 5.3), firmly press down
the soil again around the Soil
Moisture Sensor.
5.3 Setting the
Soil Moisture Sensor
General
The amount of water plants con-
sume depends on many factors:
the amount of water the plant
requires, the type of soil, amount
of sunshine, wind and many other
factors.
To find a suitable switching point
(= suitable moisture level to sup-
ply your plants with the optimum
amount of water) you must
ob-
serve the Soil Moisture Sensor
over a certain period of time
(1 - 2 weeks)
and if necessary,
adjust the settings.
Setting the Watering Time
The watering time can be set us-
ing a control knob
3
. The control
knob
3
can be adjusted using
a screw driver or coin as follows:
Turn the knob towards the minus
sign
(–)
to reduce the moisture
level and watering time. Turn the
knob towards the plus sign
(+)
to increase the moisture level
and watering time.

5. Putting into Operation
Please read these operating in-
structions carefully and observe
the notes given. Use these oper-
ating instructions to familiarise
yourself with the Soil Moisture
Sensor, the unit’s features and
proper use as well as with the
notes on safety.
A
For safety reasons, chil-
dren and young people
under 16 as well as anyone
who is not familiar with these
operating instructions may not
use the Soil Moisture Sensor.
The Soil Moisture Sensor must
only be used to control the
components recommended
by the manufacturer.
Keep these operating instruc-
tions in a safe place.

3. Operating Parts
(Fig. A)
The GARDENA Soil Moisture
Sensor is intended for private use
in domestic and hobby gardens,
exclusively for outdoor use, to
control sprinklers and watering
systems by means of water
computers
1)
taking the soil
moisture into account.
A
The Soil Moisture Sensor
must not be used for in-
dustrial purposes or in con-
junction with chemicals, food-
stuffs, easily flammable and
explosive materials.
Compliance with the operating
instructions provided by the
manufacturer is a prerequisite
to ensure proper use of the
GARDENA Soil Moisture Sensor.
The operating instructions also
contain operating, servicing and
maintenance conditions.
2. Proper Use
1) Water Computer 1030 and 1060, Water Timer Electronic T 14 and T 1030, Water Computer Plus C 1030 and Profi C 1060,
GARDENA Solenoid Valve Boxes, GARDENA Automatic Valves, GARDENA Pump Relay, and GARDENA Flower Box
Watering Set
The GARDENA Soil moisture
sensor takes the soil moisture
into account during controlled
watering.
4.1 Control knob
4
Set to Position 1
The Soil Moisture Sensor mea-
sures the amount of moisture in
the soil and closes the valve of
the respective water computer
if the soil moisture reaches the
set soil moisture level.
If the required soil moisture level
is not reached, watering is al-
lowed to proceed at the next
programmed starting time. If the
pre-set moisture level is reached
during the watering program,
the watering program is stopped.
Note :
The Soil Moisture Sensor
can also re-activate watering
during a programmed watering
time when it is dry in conjunction
with the solenoid valve boxes
of the water controller 6030.
4.2 Control knob
4
Set to Position 2
If the Soil Moisture Sensor is used
together with GARDENA flower
box watering and if automatic
program 14 is selected, watering
is switched on and off automati-
cally according to the soil mois-
ture level.
Note :
The automatic on / off
function is only possible with
GARDENA flower box watering
and by selecting watering pro-
gram 14.
