Frequently Asked Questions - TWIN 30.3048 TFA

How to install the TWIN 30.3048 weather station?

Place the indoor display on a flat surface and insert the batteries. Install the outdoor sensor in a weather-protected area and insert the batteries. The devices will synchronize automatically.

Why isn't the clock setting the time?

The radio-controlled clock receives the DCF-77 signal. Place the display near a window, avoid interference. Synchronization may take up to 10 minutes.

How to change the batteries?

For the display, open the battery compartment on the back. For the sensor, remove the cover. Use AA/LR6 alkaline batteries.

What to do if the outdoor temperature does not appear?

Check that the sensor batteries are inserted correctly and that the distance between the two devices does not exceed 100 m. Re-pair by removing and reinserting the batteries.

What is the temperature measurement accuracy?

Accuracy is ±1°C for temperature and ±5% for humidity. These tolerances are typical for a home weather station.

Can I add a second outdoor sensor?

This model is designed to work with the single outdoor sensor provided. Adding an additional sensor is not supported.

What do the weather icons on the screen mean?

The icons indicate a predicted weather trend (sunny, cloudy, rainy) based on atmospheric pressure changes. They do not replace a professional forecast.

How to set the alarms?

Press the ALARM button to enter settings. Use the + and - buttons to adjust the alarm time. Press ALARM again to confirm.

The backlight does not work, what should I do?

Check that the batteries are sufficiently charged. The backlight can be activated by pressing the SNOOZE/LIGHT button. If it remains off, replace the batteries.

How to clean the screen?

Use a soft, slightly damp cloth to wipe the screen. Do not spray liquid directly. Avoid any chemical products.
