2. Sensor Placement
Place the wireless sensor in the desired outdoor location. Ensure it is protected from direct sunlight and precipitation for accurate readings and extended lifespan. The sensor can be mounted on a wall using the integrated hanging keyhole or placed on a flat surface.
3. Initial Synchronization
After installing batteries in both units, the main unit will automatically search for the wireless sensor. The outdoor temperature reading should appear on the main unit's display within a few minutes. If the outdoor temperature does not display, press the 'RESET' button on the back of the main unit and the 'RESET' button on the sensor to re-initiate the connection process.
Operating Instructions
1. Temperature Display
The main unit displays both indoor and outdoor temperatures simultaneously. The upper section shows the outdoor temperature, and the lower section shows the indoor temperature.

3. Max/Min Temperature Records
The thermometer automatically records the maximum and minimum indoor and outdoor temperatures over a 24-hour period. These records reset automatically every 24 hours. To view the recorded maximum and minimum temperatures, press the 'MAX/MIN' button (if available, otherwise this feature is automatic and continuously updated).
4. Temperature Trend Indicator
An arrow icon next to the outdoor temperature indicates the temperature trend:
- Up arrow (β): Temperature is rising.
- Down arrow (β): Temperature is falling.
- Horizontal arrow (β): Temperature is stable.
Maintenance
1. Cleaning
Clean the thermometer's display and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the device.
2. Battery Replacement
When the low power indicator appears on the display for either the main unit or the sensor, replace the batteries promptly to ensure continuous and accurate operation. Refer to the 'Battery Installation' section for instructions.
Troubleshooting
- No outdoor temperature reading:
- Ensure batteries are correctly installed in both the main unit and the sensor.
- Press the 'RESET' button on both units to re-establish connection.
- Check the distance between the main unit and the sensor; reduce obstacles if possible.
- Replace batteries in the sensor if the low power indicator is on.
- Incorrect temperature readings:
- Ensure the sensor is not in direct sunlight or exposed to extreme heat sources.
- Verify that the sensor is protected from rain or moisture.
- Allow time for the sensor to stabilize after placement.
- Display is dim or blank:
- Replace batteries in the main unit.
- Check battery polarity.
