Operating Instructions
1. Reading the Display
The large LCD display shows the current temperature and humidity. It also provides 24-hour and all-time high/low records for both temperature and humidity.
- The top large number indicates the current temperature.
- The bottom large number indicates the current humidity percentage.
- Below the current readings, you will find the maximum (High) and minimum (Low) recorded values for the last 24 hours or all-time, depending on the selected mode.

2. Switching Temperature Units (°F/°C)
To switch between Fahrenheit (°F) and Celsius (°C):
- Locate the °F/°C button on the back of the device.
- Press the button once to toggle between the two temperature units.
3. Air Comfort Indicator
The device features three distinct face icons to indicate the air comfort level:
| Icon | Condition | Humidity Range |
|---|---|---|
| 😟 (Sad Face) | DRY | Humidity < 40% RH |
| 🙂 (Smiling Face) | COMFORT | 40% ≤ Humidity ≤ 70% RH |
| 😔 (Neutral Face) | WET | Humidity > 70% RH |
This indicator helps you determine if adjustments to your humidifier or dehumidifier are needed to maintain a comfortable environment.
