3. Operation
3.1 Temperature Unit Selection (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F):
- Locate the °C/°F button on the main unit.
- Press the button once to toggle the temperature unit.
3.2 MAX/MIN Record
The unit records the maximum and minimum temperature and humidity values over a period. To view and reset these records:
- Press the 'MIN/MAX' button once to display the maximum (MAX) recorded values.
- Press the 'MIN/MAX' button a second time to display the minimum (MIN) recorded values.
- Press the 'MIN/MAX' button a third time to return to current temperature and humidity values.
- To clear the recorded MAX/MIN values, long-press the 'MIN/MAX' button while in MAX or MIN display mode.
3.3 Backlight Function
The main unit features a backlight for improved visibility in low-light conditions:
- Press the 'LIGHT' button on the main unit to activate the backlight.
- The backlight will automatically turn off after 10 seconds to conserve battery power.

4. Placement and Mounting
The main unit and remote sensors offer various placement options for optimal monitoring.
4.1 Main Unit Placement
- The main unit can be placed on a desktop or table using its integrated stand.
- It can also be wall-mounted using the hanging hole on the back.
4.2 Remote Sensor Placement
Remote sensors can be placed in different indoor or outdoor locations. Note: The remote sensors are NOT waterproof and should be protected from direct rain or heavy moisture.
- Place sensors in areas you wish to monitor, such as a bedroom, greenhouse, office, or covered outdoor area.
- Ensure sensors are within the wireless transmission range (up to 328ft/100m in open areas) of the main unit. Walls and other obstructions may reduce this range.
- Avoid placing sensors in direct sunlight or near heat sources, as this can affect accuracy.

5. Maintenance
- Cleaning: Wipe the main unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse in water.
- Battery Replacement: Replace batteries in the main unit (3x AAA) and remote sensors (2x AAA each) when the low battery indicator appears on the display. Ensure correct polarity.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage.
6. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| No display on main unit | Batteries are dead or incorrectly installed. | Check battery polarity and replace with new AAA batteries. |
| Remote sensor not displaying data | Sensor batteries are dead; sensor is out of range; sensor channel not matched or selected. | Replace sensor batteries. Move sensor closer to the main unit. Ensure sensor channel (1, 2, or 3) is selected and long-press 'CH' on main unit to re-pair. |
| Inaccurate readings | Sensor placed in direct sunlight, near heat/cold sources, or in a high-moisture area (for non-waterproof sensors). | Relocate the sensor to a more appropriate environment, away from extreme conditions. |
| Backlight not working | Batteries are low; backlight auto-off feature. | Replace main unit batteries. Press the 'LIGHT' button again. Note that it turns off after 10 seconds. |
