7 Before commissioning
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!
8 The first steps
Follow the bullet points in order, to ensure a successful setup.
1. Setting up power supply (base station)
2. As soon as the radio signal icons for the outdoor sensors start flashing, insert the batteries into the
sensors immediately, otherwise the station will eventually switch to DCF radio signal search. No
outdoor sensors can be connected during the DCF radio signal search. If new outdoor sensors are
to be connected, please start from point 1 again.
3. When the radio signal next to the time flashes, the DCF radio signal is being searched for. During
this search, the outdoor sensors cannot be connected. The DCF search process may take up to
15 minutes and then restarts every hour if the DCF connection is not successful until the connec-
tion is successful.
9 Setting up power supply
Base device
1. Insert the DC connector into the connection socket of the base station.
2. Insert the mains plug into the power outlet.
3. The device is energized directly.
4. Wait until the indoor temperature is displayed on the base station.
NOTICE! For permanent operation, mains power supply is recommended. Alternatively a
power supply with batteries is also possible, to keep the time setting in case of power fail-
ure. Proceed as follows:
5. Remove the battery compartment cover.
6. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
7. Replace the battery compartment cover.
