The control signals are transmitted to the receiver. Frequent data
transfer between the Central Radio Control Unit and the Receiver
ensures reliable operation.
There is no danger of interference with other 433 MHz devices
(e.g. garage door opener) or other radio remote controls (e.g.
owned by your neighbours).
Compliance with the operating instructions provided by GARDENA
is a prerequisite for proper use of the Central Radio Control Unit.
The Central Radio Control Unit must only be used for controlling
the Radio Receiver for GARDENA Irrigation Valves and the
Radio Switch.
Please note
2. For Your Safety
Only use four 1.5-volt alkaline AA batteries to achieve the speci-
fied maximum operating time when the unit is not connected to
the mains. We recommend Varta and Energizer batteries.
The LCD display may go blank if the outside temperature falls
below – 10°C or rises above 60°C. This has no effect whatso-
ever on data storage or the correct transfer of data. The LCD
display will function normally again when the outside tempera-
ture returns to the normal operating range (– 10°C to 50 °C).
v If the battery status symbol flashes on the display you must
replace the batteries immediately.
To ensure good radio reception, position your Central Radio
Control Unit near a window if you prefer to keep it indoors.
The range of the radio control unit depends on the material that
must be penetrated. Concrete walls or buildings made of sheet
metal can limit the range considerably.
Extreme weather conditions (fog, rain) can also restrict the
range.
v Protect the Central Radio Control unit against moisture.
The Radio Receivers are installed in the valve boxes of the
Irrigation Valves and are safe against flooding.
The valve box must be installed such that is it safe against
flooding.
v Always ensure that the cover is closed.
