4.2 配置
Proper placement is crucial for accurate readings and reliable transmission:
- The transmitter can be hung using its integrated bracket or placed on a flat surface.
- For accurate temperature readings, place the transmitter in a location protected from direct precipitation and direct sunlight. Direct sunlight can significantly distort temperature values.
- Ensure the placement allows for optimal wireless transmission to your weather station. The outdoor transmitter has a range of up to 100 meters in an open field. Avoid major obstructions like thick walls or large metal objects between the transmitter and the weather station.

5. 操作
Once batteries are installed and the unit is placed, the transmitter will automatically begin measuring the ambient temperature.
It transmits this data wirelessly to your compatible TFA WETTERdirekt weather station at a frequency of 868 MHz. The weather station will then display the received temperature information.
6. メンテナンス
6.1 電池の交換
Replace batteries when the low battery indicator appears on your weather station or if the transmitter stops sending data. Always replace both batteries simultaneously with new AA batteries.
6.2 クリーニング
Clean the exterior of the transmitter with a soft, damp 布で拭いてください。研磨剤入りの洗剤や溶剤は、表面を傷つける恐れがありますので使用しないでください。asing または内部コンポーネント。
7。 トラブルシューティング
7.1 No Temperature Reading / No Signal
- バッテリーの状態を確認します。 電池が正しく挿入され、消耗していないことを確認してください。必要に応じて交換してください。
- 互換性の確認: Confirm that your weather station model is listed as compatible with the WD 30.3156 transmitter. Incompatibility is a common reason for communication failure.
- 近接性: Ensure the transmitter is within the 100-meter range of the weather station and that there are no major obstructions (thick walls, large metal objects) that could interfere with the 868 MHz signal.
- Re-synchronization: Refer to your weather station's manual for instructions on how to re-synchronize or pair a new outdoor transmitter.
7.2 不正確な温度測定
- 配置: Relocate the transmitter if it is exposed to direct sunlight, rain, or heat sources, as these can cause inaccurate readings.
- 換気: Ensure adequate airflow around the sensor to prevent heat buildup from affecting readings.
