switching controller :
Manual watering :
G
Reset :
Watering is activated depending on the time of programming.
Example :
Watering cycle
= 12 hours,
Watering duration
= 15 minutes.
Watering is activated every 12 hours (starting from the current time)
if the Soil Moisture Sensor reports “dry” and stops depending on
the soil moisture, but for no longer than the set duration (in this
example 15 minutes).
The Run Time button
G
can be used also to change the
watering duration of a running programme. If the new watering
duration is shorter than the watering duration already passed,
watering is stopped in the next minute of run time.
The valve can be opened or closed manually at any time. Even
a programme-controlled open valve can be closed prematurely.
Open valve manually :
v
Turn Run Time button
G
to ON.
The valve opens and closes automatically after 30 minutes.
Close valve manually :
v
Turn Run Time button
G
to OFF.
The valve closes.
If the Run-Time button
G
is turned to Reset the internal time
control of the Water Timer restarts and the 2 hour watering
break is reset.
Soil Moisture Sensor :
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 programme of the Water Timer
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
H
should be set slightly
to the right (damper).
For potting soil the switching controller
H
should be set slightly
to the left (drier).
