8. Troubleshooting

If you encounter issues with your EXCELVAN WH1175 weather station, please consider the following common solutions:

• No Display / Faint Display: Check battery polarity and ensure batteries are fresh. Replace if necessary.
• No Outdoor Data: Ensure the remote sensor is within range (max 328 feet/100m in open field) and not obstructed by thick walls or metal objects. Re-sync the sensor by removing and reinserting batteries in both units, starting with the main unit.
• Inaccurate Readings: Ensure the remote sensor is placed in a shaded, well-ventilated area, away from direct sunlight or heat sources, and protected from rain.
• Weather Forecast Not Changing: The weather forecast is based on barometric pressure changes over time. Significant changes may take several hours to register. Ensure the unit has been operating continuously for at least 24 hours for accurate forecasting.

If problems persist, please contact customer support for further assistance.
