3. Setup
3.1 Battery Installation
- Open the battery compartment cover on the back of the sensor.
- Insert 2 new AAA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
3.2 Channel Selection
The sensor allows you to select one of three channels (1, 2, or 3) to avoid interference with other wireless devices or multiple sensors. Use the small switch inside the battery compartment to select the desired channel. Ensure the selected channel matches the channel set on your main Geevon weather station for proper communication.
3.3 Sensor Placement
For accurate readings and optimal wireless transmission, consider the following placement guidelines:
- Place the sensor in a ventilated environment.
- Avoid direct sunlight or rain exposure.
- Keep the sensor away from heat sources (e.g., heating vents, appliances) and moisture sources (e.g., sprinklers, standing water).
- Ensure the sensor is within the 200ft (60m) transmission range of your main weather station. Obstacles like thick walls or metal structures can reduce the effective range.
- Mount the sensor vertically using the integrated hanging hole on the back, if desired.
4. Operation
4.1 Initial Power-On
Once batteries are inserted and a channel is selected, the sensor will automatically power on and begin transmitting temperature and humidity data every 30 seconds.
4.2 Temperature Unit Conversion (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F) temperature units, locate the small pinhole button on the sensor (often near the battery compartment or LCD). Use a thin, pointed object like a needle or paperclip to gently press this button. The display will toggle between the two units.
4.3 Data Transmission
The TX16-3 sensor transmits its data wirelessly to your compatible Geevon weather station using a 433MHz signal. Ensure your weather station is powered on and set to the same channel as the sensor to receive readings.
5. Maintenance
5.1 Battery Replacement
When the sensor's display becomes dim or stops transmitting data, it's time to replace the batteries. Follow the battery installation steps in Section 3.1. Always replace both AAA batteries at the same time with new ones.
5.2 Cleaning
Wipe the sensor's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the plastic casing or electronic components. Ensure the sensitive vents are clear of dust and debris for accurate readings.
5.3 Environmental Care
Although designed for outdoor use, extreme weather conditions can affect the sensor's lifespan. Protect the sensor from prolonged exposure to direct heavy rain, snow, or extreme temperatures outside its operating range.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No readings on weather station / Sensor not connecting | Incorrect channel selected; Dead or low batteries; Sensor out of range; Interference; Incompatible weather station. | Verify channel on sensor matches weather station; Replace batteries; Move sensor closer to weather station; Relocate sensor to avoid interference; Ensure your weather station model (208665) is compatible with the TX16-3 sensor. |
| Inaccurate temperature/humidity readings | Sensor exposed to direct sunlight/rain; Sensor near heat/moisture source; Vents blocked. | Relocate sensor to a shaded, ventilated area; Ensure vents are clear of debris. |
| Display is dim or blank | Low or dead batteries. | Replace batteries with new AAA batteries. |
