NOTICE
Avoid connection faults!
In order to avoid connection problems between the devices, the following points must be observed
during commissioning.
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 until the indoor temperature is displayed.
3. Establish power supply for the sensor.
4. Set up/operate the base unit and sensor within the effective 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 in both the base unit and the sensor and
reinsert them in the correct order so that the radio connection can be re-established. If one of the two
devices is operated via a mains power connection, the power connection for this device must also be
disconnected briefly when changing the battery. If, for example, only the batteries in the sensor are re-
placed, the signal cannot be received or can no longer be received correctly.
Note that the actual range depends on the building materials used in the building and the position of
the base unit and 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 loca-
tions for both the base unit and the outdoor sensor. Sometimes a shift of just a few centimetres is
enough!
11 Establish power supply
Base unit
1. Insert the DC plug into the connection socket on the base unit.
2. Insert the Euro plug into the mains power socket.
3. The device is powered on directly.
Installing the backup battery:
1. Remove the battery compartment cover.
2. Insert the battery into the battery compartment. Make sure that the battery terminals are correctly
aligned (+/-).
3. Replace the battery compartment cover.
Wireless sensor
4. Remove the screw on the battery compartment cover with a suitable Phillips screwdriver and re-
move the battery compartment cover.
5. Insert 2 x AA size batteries into the battery compartment. Make sure that the battery terminals are
correctly aligned (+/-).
6. Replace and screw on the battery compartment cover.
