Setup
1. Battery Installation:
The main unit and the wireless outdoor sensor each require 2 x LR03 AAA batteries (not included).
- Open the battery compartment (C1 for main unit, C2 for outdoor sensor) on the back of each device.
- Insert 2 x LR03 AAA batteries into each compartment, ensuring correct polarity (+/-).
- Close the battery compartments securely.
Note: It is recommended to insert batteries into the outdoor sensor first, then the main unit, to ensure proper pairing.
2. Initial Pairing and Placement:
Once batteries are installed, the main unit will automatically attempt to connect with the outdoor sensor. The outdoor sensor has a transmission range of up to 60 meters in an open area.
- Main Unit Placement: The main unit can be placed on a flat surface using its integrated stand or mounted on a wall. Choose a central location indoors for optimal indoor temperature and humidity readings.
- Outdoor Sensor Placement: Place the outdoor sensor in a sheltered location outdoors, away from direct sunlight and rain, to ensure accurate readings and prolong its lifespan. Ensure it is within the 60-meter transmission range of the main unit.

3. Setting Time, Date, and Language:
After power-on, you may need to set the time, date, and preferred language for the day of the week display.
- Press and hold the "MODE" button (B1) for a few seconds to enter time setting mode.
- Use the "UP" (B3) and "DOWN" (B4) buttons to adjust the flashing value (e.g., hour, minute, year).
- Press "MODE" again to confirm the setting and move to the next value.
- Continue until all settings (time, 12/24 hour format, year, month, day, day of week language) are configured.
- The day of the week can be displayed in English, German, Italian, French, Russian, Spanish, Dutch, or Danish.
- Press "MODE" one last time or wait for 15 seconds for the settings to be saved automatically.
Note: The device supports DCF time control for Germany. If you are in Germany, the time will automatically synchronize with the DCF signal. For other regions, manual time setting is required.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | Batteries are dead or incorrectly inserted. | Check battery polarity and replace with new LR03 AAA batteries. |
| Outdoor temperature/humidity not displayed or flashing. | No connection to outdoor sensor; sensor batteries low; sensor out of range; interference. |
|
| Incorrect temperature/humidity readings. | Sensor exposed to direct sunlight, heat sources, or moisture. | Relocate the sensor to a sheltered area, away from direct elements and heat/cold sources. Allow time for readings to stabilize. |
| Time is incorrect (outside Germany). | Time was not set manually or reset after power loss. | Manually set the time and date using the "MODE" button as described in the Setup section. |
