9. Initial operation


First commission the outdoor sensor for the temperature/air humidity and then the rain and
wind sensor. Then insert the batteries into the weather station!
This is the only way to ensure the correct function of the devices.
When performing the initial installation, you need the altitude coordinates of your region. This is used
later on to calculate the correction value for the air pressure. To obtain the altitude of your region (an
approximate value is sufficient), consult a map or refer to the website of your city/region.
Prior to installing the rain and wind sensors in a permanent location, we recommend performing a
function test with all devices.
The radio range of 30m (rain sensor, wind sensor and outdoor sensor for temperature/air humidity) is
the so-called "free field range", meaning the maximum range in case of direct sight connection between
the transmitter (sensors) and the receiver (weather station).
However, this ideal configuration may not work in practice, as furniture, walls, windows or plants may
be located between the sensors and the weather station.
Another source of interference which significantly reduces the range is the proximity to metal parts,
electric/electronic devices or cables. Reinforced concrete ceilings, vacuum metallised insulated glass
windows or other devices operating on the same transmission frequency.
Do not place the devices directly next to each other when performing the function test. Keep a distance
of at least 50 cm; otherwise the transmitters may interfere with each other.
a) Temperature/air humidity sensor
• Open the battery compartment on the back by unscrewing the 2 screws (14) of the battery compartment cover (15)
beforehand.
• Insert two batteries of type AA/mignon with correct polarity into the battery compartment (17, observe positive/+
and negative/-).
• Replace the cover of the battery compartment (15) again and screw it down firmly.
• When selecting the installation site for the temperature/air humidity sensor, make sure that it is protected from
precipitation (e.g. beneath an eave). Otherwise, the sensor would no longer measure the air temperature.
The sensor may also not be exposed to direct sunlight, as this would falsify the measuring values.
The opening for wall mounting (13) serves to hang the temperature/air humidity sensor on a screw or similar.
