How to set up the Sensor Controller - automatic
watering
Sunrise and Sunset is the best time to water your garden to avoid
evaporation and leaf scorch. The Daylight sensor automatically
adjusts the watering schedule to coincide with the changing time
for sunrise and sunset.
Cloudy or overcast mornings and evenings might cause a slight
delay to the watering times, but these are not significant to have
any adverse effects on your garden.
1
Rotate the control dial to select from the 3 marked sections –
Sunrise (once a day), Sunset (once a day) or Sunrise and Sunset
(twice a day). (See Fig. 5)
2
Choose from the required watering durations – 2, 5, 10, 20, 30 or
60 minutes of watering.
How to turn off the Sensor Controller
If you do not want the controller to automatically come on turn the
rotary dial to the “OFF” position. You can still use the
button to
manually water your garden.
Initial synchronisation period
When you install new batteries there is a 6 hour lockout period to
prevent the controller from watering while you are setting up your
system. After a 24 hour cycle of Sunrise and Sunset the controller
will be synchronised with the changing light levels. You can
manually water your garden using the
button during the 6 hour
lockout period.
Positioning your Sensor Controller outdoors
It is important that your water controller is in an outdoor location.
Do not point the control panel directly towards outdoor security
lights or other bright lights that come on during the night as
these might interfere with the recorded light levels and cause the
controller to come on at the wrong time.
Ideally, you should not set up your controller in a heavily shaded
passageway or behind buildings where light levels remain low
all day long. Do not position the controller inside buildings such
as garages or sheds where it will not receive natural daylight to
function correctly.
The controller is designed to be positioned directly underneath an
outdoor tap. Do not position the controller on its side or lying on the
ground whereby rainwater cannot flow away from the product.
1 hour delay
(when using 2 Sensor Controllers together)
If you install two Sensor Controllers you might want to stagger the
start times to prevent pressure loss when two appliances are used
simultaneously – for example sprinklers.
Remove the delay plug from the storage location on the back of
the control panel (Fig. 2) and fit the plug on the location below the
batteries.
With the plug inserted the one hour delay affects all automatic
watering. The delay period of one hour cannot be changed.
Manual operation (water now)
You can turn on the water controller at any time by pressing the
button once. Press again to turn off at any time.
