1. Where to Use Your GARDENA Water Computer
The GARDENA Water Computer is intended for private use in
domestic and hobby gardens, exclusively for outdoor use, to
control sprinklers and watering systems.
The Water Computer can be used for automatic watering during
holidays.
The GARDENA Water Computer must not be used for
industrial purposes or in conjunction with chemicals,
foodstuffs, easily flammable and explosive materials.
Intended use:
Please note:
2. Safety Instructions
Battery:
To ensure the Water Computer runs safely,
only a 9V alkaline manganese battery
(alkaline) type IEC 6LR61 must be used.
In order to stop the Water Computer 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.

116
GB
Setting up
The Water Computer 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 Computer 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 60 °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.
vOnly use clear fresh water.
The minimum operating pressure is 0.5 bar,
the maximum operating pressure is 12 bar.
Avoid tensile strain.
vDo not pull the hose connected to the
Water Computer.
If the controller is removed when the valve
is open, the valve remains open until the
controller is fitted again.
3. Function
With the Water Computer, the garden can be watered fully auto-
matically up to 3 times a day at any time of day (every 8 hours).
Sprinklers, a sprinkler system or a drip head watering system
can be used for watering.

117
GB
The Water Computer carries out watering fully automatically
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.
The watering program is easily selected via the rotary knob.
A watering program comprises the watering start time, duration
and cycle.

Apart from scheduled watering there is also the option of including
how damp the soil is or rainfall into the watering programme.
Note:
If the soil is damp enough, the programme will be stopped, or
a programme will be prevented from starting. Manual operation
is possible at all times.
1. Remove controller Afrom the housing of the Water Computer
(see 4. Putting Your Water Computer into Operation “Insert
battery”).
2. Place soil moisture sensor in the watered area – or – place
rain sensor (with extension cable if necessary) outside the
watered area.
3. Run the sensor cable Fthrough the opening of the housing.
4. Disconnect the cover Gand insert the sensor cable plug F
into the sensor connection Hof the water computer.
It can take up to 1 min. until the status of the sensor is shown
on the display.
An adapter cable may be required to connect older sensors,
