NOTICE
Avoid connection faults!
In order to avoid connection problems between the devices,
the following points must be observed during commission-
ing.
1. Place the base unit (receiver) and sensor (transmitter)
as close together as possible.
2. Connect the power supply to the base unit and wait un-
til the indoor temperature is displayed.
3. Establish power supply for the sensor.
4. Set up/operate the base unit and sensor within the ef-
fective transmission range.
5. Make sure that the base unit and the radio sensor are
set to the same channel.
When changing the batteries, always remove the batteries
from both the base unit and the sensor and reinsert them in
the correct order so that the radio link can be re-estab-
lished. If one of the two devices is operated via a mains
power connection, the power connection must also be
briefly disconnected for this device when the batteries are
changed. If, for example, only the batteries in the sensor
are replaced, the signal may subsequently not be received
at all or not be received correctly.
Note that the actual range depends on the respective con-
struction materials used for the buildings as well as the re-
spective position of the base unit and the outdoor sensor.
External influences (various radio transmitters and other
sources of interference) can greatly reduce the possible
range. In such cases, we recommend finding other locations
for both the base unit and the outdoor sensor. Sometimes
moving the sensor by just a few centimeters is enough!
