c) External sensor for temperature/air humidity
• Open the battery compartment on the rear by unscrewing two screws of the battery compartment lid beforehand.
The battery compartment lid is inserted at the foot in the housing's underside, fold it upwards (at the
screw holes) a bit; now it can be removed carefully.
• Prior to inserting the batteries, the transmission channel is to be set via the sliding switch (20) if you operate more
than one outdoor sensor.
Also in the event of reception failures (e.g. if a weather station of the same or similar design is used in close
proximity) you should try to select a different channel.
In order for the outdoor sensor to recognise the change to another channel, you have to remove the
batteries for a few seconds and then reinsert them afterwards. Now check if the correct channel number
is shown at the top left in the display of the outdoor sensor.
The menu of the weather station enables you to preset whether only the data of one individual outdoor
sensor shall be displayed (e.g. only the temperature/air humidity measuring values of a single outdoor
sensor, e.g. channel 3) or if the switch shall take place automatically (data of the 2 or 3 outdoor sensors
will be shown one after another).
If you use more than one outdoor sensor, each one of them must be set to a different channel!
• Insert two batteries of type AAA/micro in the battery compartment (21) observing the correct polarity. In the battery
compartment you will find the corresponding markings for the polarity. If the batteries are inserted wrongly, the
outdoor sensor does not work.
• By pressing the "°C/°F" (19) button the temperature display can be switched between "°C" (degree Celsius) and
"°F" (degree Fahrenheit).
• The "TX" button can be used to send a data package of measured values to the weather station (e.g. when replacing
the batteries or for test purposes). Normally, this is not required and thus, you can close the battery compartment
lid; see below.
• Insert the battery compartment lid with the 3 plastic lugs in the housing and then close it. Now tighten it with the
two screws that you previously removed.
• The installation site of the outdoor sensor should be chosen so that it is protected from precipitation (e.g. under a
roof projection), otherwise the sensor won't measure the air temperature.
The sensor must not be exposed to direct insolation since this also leads to faulty measurements due to the sun
exposure.
• By means of the opening for wall mounting (17) the outdoor sensor can be installed on the wall e.g. with a screw,
hook or nail.
If you wish to place the outdoor sensor on an even surface (e.g. window board), make sure it cannot topple over
or fall down. This will damage the outdoor sensor!
d) Weather station
• Connect the low-voltage socket (5) on the weather station with the circular connector of the wall plug transformer
provided.
• Plug the wall plug transformer in a mains socket.
• If there is no display in the weather station after a few seconds, briefly press the "
the weather station (or the key on the IR remote control with the same labelling).
• For the next 4 minutes the weather station performs a search for the available outdoor sensors; the symbol "
flashes in the display of the weather station.
