Setup
- Battery Installation:
Open the battery compartment on the back of the sensor. Insert two (2) AAA batteries, ensuring correct polarity (+/-). Close the battery compartment securely.
Important Battery Notes: Do not use heavy-duty or rechargeable batteries. For low-temperature conditions, lithium batteries are recommended as alkaline batteries may perform improperly. Do not mix old and new batteries.
- Channel Selection:
Locate the channel switch inside the battery compartment or on the sensor. Select the desired channel (1, 2, or 3). If using multiple sensors, assign a unique channel to each sensor.
- Pairing with Main Unit:
Once batteries are installed and a channel is selected, the sensor will automatically begin transmitting data. Ensure your compatible Geevon weather station or thermometer is powered on and within range to receive the signal. Refer to your main unit's manual for specific pairing instructions if needed.
- Sensor Placement:
For accurate readings, place the sensor in a ventilated outdoor environment. Avoid direct sunlight, as this can cause artificially high temperature readings. Keep the sensor away from heat sources (e.g., vents, appliances) and moisture sources (e.g., sprinklers, gutters).
Ensure the sensor is within 200 feet (60 meters) of the main unit. Maintain a distance of at least 3 feet (1 meter) from electronic devices that may cause wireless interference, such as TVs, microwaves, computers, or radios.
Compatibility Note: This sensor is compatible with Geevon Weather Station models 208270, 208667, 208664, 215019, 8688, and Indoor/Outdoor Thermometer model 228646. Please verify your main unit's compatibility before purchasing or using this sensor.
Operating Instructions
The Geevon TX19 sensor operates automatically once properly set up. It continuously monitors outdoor temperature and humidity and transmits this data wirelessly to your compatible Geevon weather station or thermometer.
- Data Transmission: The sensor transmits updated data every 30 seconds.
- Multi-Location Monitoring: If you are using multiple TX19 sensors (up to three), your main weather station will display temperature and humidity readings for each assigned channel, allowing you to monitor different outdoor locations simultaneously.
No user interaction is required for daily operation beyond initial setup and periodic battery replacement.
Maintenance
- Battery Replacement: The sensor requires two (2) AAA batteries. Replace batteries approximately every 6 months, or when the low battery indicator appears on your main weather station. Follow the battery installation guidelines in the Setup section.
- Cleaning: Periodically wipe the exterior of the sensor with a soft, damp cloth. Do not use abrasive cleaners or immerse the sensor in water. Ensure no water or other liquids enter the sensor's internal components.
- Optimal Placement: Regularly check the sensor's placement to ensure it remains in a ventilated area, away from direct sunlight, heat sources, and excessive moisture, to maintain accurate readings.
