Features of Sensors
Wind Sensor
The wind sensor measures wind speed and transmits it to the thermo-hygro sensor, which then relays it to the base station.
Rain Sensor
The rain sensor measures rainfall and transmits it to the thermo-hygro sensor, which then relays it to the base station. It is powered via a cable connection from the thermo-hygro sensor.
3. Set Up Guide
3.1 Battery Install
Setting up using batteries:
Diagram Description: A diagram shows the thermo-hygro sensor with labeled parts: LED Indicator, Sensor Sockets, Battery Compartment, and Battery Cover. It also indicates where the wind and rain sensors connect.
Note: To prevent damage, ensure correct battery polarity when inserting batteries. Use good quality Alkaline batteries and avoid rechargeable ones.
- Pull away the shower-proof casing of the thermo-hygro sensor to access the two sockets for the wind and rain sensors.
- Connect the attached cables of the wind and rain sensors to their corresponding sockets on the thermo-hygro sensor. Ensure correct orientation (avoid swapping rain and wind sockets).
- Open the battery cover below the sensor sockets on the thermo-hygro sensor and insert 2 x AA, 1.5V Alkaline batteries (included). Close the cover.
- Open the base station's battery cover (located on the back) and insert 3 x AA, 1.5V Alkaline batteries (not included). Close the cover.
Upon powering up, the thermo-hygro sensor's LED indicator will light up for 4 seconds. A random security code is transmitted for synchronization with the base station. The base station will emit a short beep and display all LCD segments for 3 seconds before entering learning mode.
Note: Do not press any keys before the indoor station displays data from the remote sensor. After indoor and outdoor data are visible, you can place the remote sensor outdoors and set the time. If no temperature reading appears, ensure units are within range or repeat the battery installation. Pressing a key before receiving the temperature signal requires repeating the battery installation procedure. Wait at least 10 seconds before re-inserting batteries for a proper reset.
Note: If the transmitter battery is changed, the base station will resynchronize within 3 hours. To speed this up, re-installing the base station battery will initiate learning of the new security code, but previous weather data and alarm values will be lost.
Note: A low battery indicator will appear on the base station's LCD when batteries need replacement. Please dispose of used batteries responsibly at designated points and never in fire.
3.2 Mounting
1) Base Station:
The base station can be placed on any flat surface using its foldable leg or wall-mounted using the hanging holes on the back. Ensure radio signal reception before permanent mounting.
2) Remote Sensor:
For accurate readings, mount the remote sensor mast securely on a horizontal surface in an open area, away from trees or obstructions that could affect rainfall or wind speed measurements.
Diagram Description: Diagrams show the mounting of the wind sensor onto a mast (front and back views), the rain sensor, and the thermo-hygro sensor with a solar panel. Another diagram illustrates fixing the entire assembly to a pole using adjustable hoops. A close-up shows cable connections.
a) Mounting the wind sensor onto a mast:
First, check that the wind-fan rotates freely. Mount the wind sensor using the provided screw onto a mast, ensuring the wind can travel around the sensor unhindered from all directions.
b) Mounting the rain sensor:
(Diagram description for rain sensor mounting)

d) Mounting the thermo-hygro sensor:
Mount the thermo-hygro sensor similarly to the rain sensor.
e) Fixing the whole set to a pole:
Use the two adjustable hoops to fix the complete assembly to a pole.
After fixing the wind and rain sensors onto the mast, connect their cables to the corresponding thermo-hygro sensor sockets:
- Anemometer cable connects to the 'Wind' input on the thermo-hygro sensor.
- Rain sensor cable connects to the 'Rain' input on the solar panel.
- Solar panel cable connects to the 'Rain' input on the thermo-hygro sensor.
The Solar Transmitter
The solar transmitter uses solar energy to power connected instruments. It uses AA size lithium batteries. Ensure solar receptors are exposed to sunlight and connection cables are securely plugged in for proper function.
For optimal results, orient the solar panel:
- Facing north if in the southern hemisphere.
- Facing south if in the northern hemisphere.

4.2 Weather Forecasting
The weather forecasting is represented by four icons: Sunny, Partly Cloudy, Cloudy, and Rainy. These icons update based on significant changes in air pressure to reflect the predicted weather.
4.3 Weather Forecast Tendency Indicator
The tendency indicator arrow shows air pressure trends. A rightward arrow [→] indicates increasing air pressure and improving weather. A leftward arrow [←] indicates decreasing air pressure and worsening weather. If the weather is changing, the tendency indicator (animated arrows) will flash; it becomes steady once conditions stabilize.
Diagram Description: Examples of changing weather icons are shown, illustrating transitions between different weather states with corresponding tendency arrows.
4.4 Storm Warning Indicator
The storm warning feature activates if there is a pressure drop exceeding a set threshold (default 4hPa) within 3 hours. When activated, the storm icon (clouds with rain) and tendency arrows will flash for 3 hours.
Notes on Pressure Sensitivity: The pressure threshold for weather forecasting can be set between 2-4hPa (default 3hPa). Areas with frequent pressure changes may require a higher setting. For example, a 4hPa setting means a change of at least 4hPa is needed to register as a weather change.

6. Problems and Interference with Operation
| Problem & Cause | Remedy |
|---|---|
| Distance between transmitters and receiver too long | Reduce distance between transmitters and receiver. |
| High shielding materials (thick walls, steel, concrete, aluminum foil) | Find a different location for sensors and/or receiver. See 'transmission range' information. |
| Interference from other sources (wireless radio, headset, speaker, etc. operating on the same frequency) | Find a different location for sensors/base station. Neighbors' electrical devices on the same frequency can also cause interference. |
| No reception after adding extension cables | Find a new location for sensors/base station. |
| Poor contrast LCD or no reception or low batteries in sensors or receiver | Change batteries (check low battery indicator on LCD). |
| Temperature, humidity, or air pressure is incorrect | Check/replace batteries. If multiple remote sensors are used, check location with corresponding "boxed numbers" or move away from heat/cold sources. Adjust relative air pressure using a reliable source (e.g., TV/radio). |
