4.1 Base Station Display Elements

Figure 2: Close-up of the Weather Station Display.

The display shows: atmospheric pressure (hPa), weather forecast icons (sunny, partly cloudy, cloudy, rainy), outdoor channel indicator (CH 1 OUT), outdoor temperature (°C/°F) and humidity (%), and indoor temperature (°C/°F) and humidity (%).

• Atmospheric Pressure: Displayed in hPa, with trend arrows.
• Weather Forecast Icons: 4 symbols (sunny, partly cloudy, cloudy, rainy) based on pressure changes.
• Outdoor Temperature & Humidity: From the wireless sensor.
• Indoor Temperature & Humidity: Measured by the base station.
• Channel Indicator: Shows which outdoor sensor channel is currently displayed (up to 3 sensors supported).

4.2 Base Station Control Buttons (Rear)

The rear panel features four control buttons: DOWN, UP, CHANNEL, and SET. These buttons are used for navigating settings, adjusting values, and switching between outdoor sensor channels.

• DOWN: Decreases values, navigates menus.
• UP: Increases values, navigates menus.
• CHANNEL: Switches between outdoor sensor channels (if multiple sensors are paired).
• SET: Enters settings mode, confirms selections.

5. Setup

5.1 Battery Installation

1. Outdoor Sensor: Open the battery compartment on the back of the outdoor sensor. Insert 2 x 1.5V AAA batteries, observing correct polarity (+/-). Close the compartment.
2. Base Station: Open the battery compartment on the back of the base station. Insert 2 x 1.5V AAA batteries, observing correct polarity (+/-). Close the compartment.
3. The base station will emit a short beep and all LCD segments will light up briefly. It will then display indoor temperature and humidity. The outdoor sensor data will appear shortly after.

5.2 Sensor Pairing

The base station will automatically attempt to connect to the outdoor sensor upon battery insertion. Ensure the sensor is within range (max. 100m in open air). If connection is not established, press the "CHANNEL" button on the base station to initiate a manual search.

The station supports up to three outdoor sensors. To add additional sensors, repeat the battery installation process for each new sensor. Use the "CHANNEL" button to cycle through and display data from different sensors.

5.3 Initial Settings (Atmospheric Pressure)

The atmospheric pressure needs to be set during initial setup for accurate weather forecasting. Consult a local weather service or online source for the current atmospheric pressure in your area.

1. Press and hold the "SET" button until the atmospheric pressure value flashes.
2. Use the "UP" or "DOWN" buttons to adjust the value to your local atmospheric pressure.
3. Press "SET" again to confirm and exit the setting mode.

5.4 Placement

• Base Station: Place the base station indoors on a flat surface or mount it on a wall. Avoid placing it near heat sources, direct sunlight, or areas with high electromagnetic interference.
• Outdoor Sensor: Position the outdoor sensor in a sheltered location, protected from direct rain and snow. Ensure good air circulation around the sensor. Avoid direct sunlight to prevent inaccurate temperature readings. The maximum range is 100m (open field).

6. Operating the Weather Station

6.1 Displaying Temperature and Humidity

The base station continuously displays indoor temperature and humidity, along with the selected outdoor sensor's temperature and humidity.

6.2 Switching Temperature Units (°C/°F)

To switch between Celsius and Fahrenheit, briefly press the "UP" button outside of setting mode.

6.3 Weather Forecast

The weather station provides a forecast for the next 12-24 hours using four weather icons: sunny, partly cloudy, cloudy, and rainy. These forecasts are based on changes in atmospheric pressure. The accuracy of the forecast improves after the initial atmospheric pressure setting has been stable for several hours.

6.4 Atmospheric Pressure Trend

Arrows next to the atmospheric pressure display indicate whether the pressure has risen, fallen, or remained stable over the last hour. This helps in understanding short-term weather trends.

7. Maintenance

7.1 Cleaning

Clean the device with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.

7.2 Battery Replacement

Replace batteries when the low battery indicator appears on the display. Always replace all batteries in a unit (base station or sensor) simultaneously to ensure optimal performance. Dispose of old batteries responsibly.
