Introduction
Thank you for choosing the TFA Dostmann 30.3016.01 Wave Radio Thermometer. This device provides accurate indoor and outdoor temperature readings, along with time and date display. It utilizes a wireless outdoor sensor to transmit temperature data to the main unit. Please read this manual carefully to ensure proper setup and operation.
The main unit measures indoor temperature, while the wireless outdoor transmitter measures outdoor temperature. This system helps monitor your living climate and can contribute to energy saving by optimizing heating. The device also stores minimum and maximum temperature values and displays the current time and date.

2. Initial Synchronization and Placement
After battery insertion, the main unit will automatically search for the outdoor sensor and the radio time signal. This process may take a few minutes.
- Place the outdoor transmitter in a sheltered location, away from direct sunlight and rain, to ensure accurate readings and prolong its lifespan. Ensure it is mounted vertically as designed to prevent water ingress into the battery compartment.
- Position the main unit indoors, away from electronic devices that might cause interference (e.g., TVs, computers).
- Ensure the distance between the main unit and the outdoor sensor is within the effective transmission range (typically up to 100 meters in open air, less with obstacles).
- The time and date will automatically synchronize via the radio signal.
Operating Instructions
Display Information
The display shows the following information:
- Indoor Temperature: Measured by the main unit's internal sensor.
- Outdoor Temperature: Received from the wireless outdoor transmitter.
- Time: Automatically synchronized via radio signal.
- Date and Day of the Week: Automatically synchronized via radio signal.
Viewing Minimum and Maximum Values
The device stores the highest (maximum) and lowest (minimum) temperatures recorded since the last reset. To view these values:
- Press the "MAX/MIN" button (or similar, refer to device buttons) once to display the maximum recorded indoor and outdoor temperatures.
- Press the "MAX/MIN" button again to display the minimum recorded indoor and outdoor temperatures.
- To clear the recorded maximum and minimum values, press and hold the "MAX/MIN" button for a few seconds while the respective values are displayed.
Manual Time and Date Setting (if automatic synchronization fails)
In rare cases where the radio time signal is not received, you may need to set the time and date manually. Refer to the specific buttons on your device (e.g., "SET", "MODE", "UP", "DOWN").
- Press and hold the "SET" or "MODE" button until the time display starts flashing.
- Use the "UP" or "DOWN" buttons to adjust the hour, then press "SET" or "MODE" to confirm and move to the minutes.
- Repeat for minutes, year, month, and day.
- Press "SET" or "MODE" one last time to exit the setting mode.
Maintenance
Cleaning
Clean the device with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.
