Usage :
The water requirement of plants depends on many factors, e.g.
type of plant, soil, sunshine, wind. To find the suitable switching
point of the Soil Moisture Sensor, it has to be observed during
irrigation over a period of approx. 1 - 2 weeks and re-adjusted
if necessary. If the soil moisture has exceeded the switching
point selected, the watering program of the Water Computer
is terminated prematurely or an outstanding irrigation process
blocked.
On delivery, the switching controller is set to the centre position,
which is suitable for normal non-forest soils (loamy humus).
For sandy soils the switching controller
slightly to the right (damper).
For potting soil the switching controller
slightly to the left (drier).
Increase soil moisture level :

species), turn the switching controller
"Damp" (e.g. with a coin).
Reduce soil moisture level :
v If the soil seems too damp for an application (type of soil or
plant species), turn the switching controller
towards "Dry" (e.g. with a coin).

To keep the soil moisture level as constant as possible, irrigation
should be carried out with short watering cycles and short wate-

which have a watering time of < 5 min.
