4.2 Pairing with Main Weather Station
The sensor is designed to work with compatible VIFLYKOO weather stations, including models EM3378UC, 3390F, 3383D, 378QX, 3378YC, and 3383C. Refer to your main weather station's manual for specific pairing instructions. Generally, the process involves:
- Ensure both the sensor and the main station have fresh batteries installed.
- Select a channel (CH1, CH2, or CH3) on the outdoor sensor using the Channel Button. Ensure this matches the channel selected on your main weather station for outdoor sensor data.
- Initiate the sensor search function on your main weather station (refer to its manual).
- Притисните тастер ТКС Свитцх button on the outdoor sensor to send a signal. The signal light will flash.
- The main station should detect and display the sensor's data within a few minutes. If not, repeat the steps, ensuring the devices are within range.
4.3 Монтажа сензора
For accurate readings, choose a mounting location that is protected from direct sunlight and heavy precipitation, but still allows for good air circulation. The sensor can be mounted flexibly:
- Монтажа на зид: Use the integrated wall hanging hole and a suitable screw (not included) to secure the sensor to a wall, eave, or fence.
- Монтажа носача: The sensor also features a fixing bracket for alternative mounting options.
The wireless transmission range is approximately 100-110 meters in open, unobstructed areas. With physical obstacles like walls, the effective range is about 50-60 meters. Position the sensor within this range of your main weather station.
5. Операција
5.1 Избор јединице температуре (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F) temperature display, press the Прекидач за ° Ц / ° Ф button located inside the battery compartment. The display on the sensor will update accordingly.
5.2 Reading Data
The sensor's small LCD screen displays the current temperature and humidity. For a comprehensive view and historical data, refer to your main weather station's display.

6. Одржавање
6.1 Чишћење
Wipe the sensor periodically with a soft, damp крпу. Не користите абразивна средства за чишћење или раствараче, јер могу оштетити цasinг или унутрашње компоненте.
6.2 Замена батерије
When the battery indicator on the sensor or main station shows low power, replace both AA batteries with new ones. Follow the battery installation steps in Section 4.1. After replacing batteries, you may need to re-pair the sensor with your main weather station.
КСНУМКС. Решавање проблема
- No readings on main station:
- Check if batteries are correctly installed and have sufficient power in both the sensor and the main station.
- Ensure the sensor and main station are set to the same channel.
- Verify that the sensor is within the effective transmission range (50-60m with obstacles, 100-110m unobstructed).
- Try re-pairing the sensor with the main station (refer to Section 4.2).
- Нетачна очитавања:
- Ensure the sensor is mounted in a location protected from direct sunlight, which can cause artificially high temperature readings.
- Check for any obstructions around the sensor that might impede air circulation.
- Compare readings with a known accurate thermometer/hygrometer to confirm discrepancy.
- Sensor display is blank:
- Замените батерије новим.
