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.
4
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 to 15 pieces of
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.
v Only use clear fresh water.
The minimum operating pressure is 0.5 bar,
the maximum operating pressure is 12 bar.
Avoid tensile strain.
v Do 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 automatically up to 6 times a day at any time of day. Sprinklers, a
sprinkler system or a drip head watering system can be used for
watering.
5
GB
The Water Computer carries out watering fully automatically
according to the set programs 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 programmes are easily entered using the controls.
A watering program comprises the watering duration, cycle and
start time.
