Before commissioning

NOTICEAvoid 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 a 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 replaced, 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 locations for both the base unit and the outdoor sensor. Sometimes a shift of just a few centimetres is enough!Though the remote unit is weatherproof, it should be placed away from direct sunlight, rain or snow.

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, the mains power supply is recommended. Alternatively a power supply with batteries is also possible, to keep the time setting in case of power failure. 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.
  8. Wait until the indoor temperature is displayed on the base station.NOTICE! When switching from mains power supply to battery power supply or vice versa, the power supply is being disabled for a short moment for technical reasons. Exception: permanent battery operation. Remote sensor
  9. Remove the battery compartment cover.
  10. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
  11. Set the channel selector switch to the desired channel.NOTICE! This weather station can be operated with one or more remote sensors. Each remote sensor being connected must be operated on a different channel. If only one remote sensor is connected, it should be operated on channel 1.
  12. Replace the battery compartment cover.

Automatic time setting

After the power is restored, the unit automatically searches for the radio signal. It takes about 3-8 minutes to complete this process. If the radio signal is received correctly, the date and time are set automatically and the reception symbol is displayed. If no radio signal is received, proceed as follows:

  1. Press the DOWN button for approx. 2 seconds to initi-ate the reception of the radio signal again.
  2. If no radio signal is still received, the time setting must be made manually. Read the detailed manual for more information about manual time and alarm settings (see download information on page 2).

Manual time setting

Receiving measurements automatically

Once the power supply is enabled, the base station will display the measurement readings indoors. Readings from the outdoor sensor will be displayed within 3 minutes after powering it on. If no signal is received, proceed as follows: Press the CH button for about 3 seconds to initiate reception of measurements again.

Weather trend

The weather station will calculate a weather trend for the next 12 hours on basis of the measured values.
