5.2 Unit Switching (°C/°F)
Press the 'MEM/℃/℉' button on the main unit to switch between Celsius (°C) and Fahrenheit (°F) temperature units.
5.3 Temperature and Humidity Alarm
The device features Hi/Lo temperature and humidity alarm functions. You can manually set maximum and minimum alert values. An audible alarm will sound when the readings reach these predefined points.

5.4 Max/Min Records
The main unit automatically updates Max/Min temperature and humidity data every 24 hours. Press the 'MEM/℃/℉' button to view the maximum and minimum records for the past 24 hours.
5.5 Comfort Level Indicator
The display includes a comfort level indicator (Dry, Comfort, Wet) based on current humidity levels, helping you quickly assess your living conditions.
Image: A visual representation of the comfort symbol feature, showing icons for 'Dry' (humidity < 40%), 'Comfort' (40% ≤ humidity ≤ 70% & 20°C ≤ temperature ≤ 28°C), and 'Wet' (humidity > 70%).
6. Placement Guidelines
6.1 Main Unit Placement
The main unit can be placed on a desktop using its integrated stand or mounted on a wall using the hanging hole. Choose a central location indoors for optimal reception from remote sensors.
6.2 Remote Sensor Placement
Place remote sensors in desired locations such as bedrooms, wine cellars, basements, gardens, greenhouses, grow tents, or offices. The wireless transmission range is up to 60 meters (200 feet) in open areas. Ensure outdoor sensors are protected from direct sunlight and rain, as they are splash-proof (IPX4) but not fully waterproof.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | Batteries are dead or incorrectly installed. | Replace batteries with new ones, ensuring correct polarity. |
| Remote sensor not transmitting data. | Sensor batteries are dead; sensor is out of range; interference. | Replace sensor batteries. Move sensor closer to the main unit. Avoid placing near large metal objects or electronics that may cause interference. Press 'TX' button on sensor. |
| Inaccurate readings. | Sensor exposed to direct sunlight/heat source or moisture. | Relocate sensor to a shaded, well-ventilated area away from direct heat or moisture. Allow time for readings to stabilize. |
| Alarm not sounding. | Alarm settings are incorrect or disabled. | Check and adjust the Hi/Lo alarm settings as per operating instructions. |
