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.
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.
Programming
v Program the Water Computer with the tap
turned off.
In this way you can avoid getting wet when
trying out the manual On/Off function (man.
On/Off). You can remove the control unit from
the housing to program 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.
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 programme is easily entered using the controls.
