Notes on radio installations
When planning facilities with devices that communicate via radio, adequate radio
reception must be guaranteed. The range of wireless control will be limited by legal
regulation and structural circumstances. Avoid sources of interference and obstacles
between receiver and transmitter, that could disturb the wireless communication. Those
would be for example:
•
Walls and ceilings (especially concrete).
•
Metal surfaces next to the wireless participants (e. g. aluminium construction of a
conservatory).
•
Other wireless devices and powerful local transmitters (e.g. wireless
headphones), which transmit on the same frequency (868,2 MHz). Please
maintain a minimum distance of 30 cm between wireless transmitters for that
reason.
Commissioning
ATTENTION!
If a device is brought from a cold to a warm area, condensation
can form. Before starting the device up, please ensure there is
no moisture inside it (if necessary leave to dry).
After the system has been wired and the connections have been checked, please
proceed as follows:
•
Switch on the power supply voltage of the weather station.
•
Insert batteries in the operating unit as described in chapter “Insert batteries”.
•
The display of the operating unit now indicates that the radio connection between
weather station and operating unit is not taught in.
