Operating Instructions
Display Information:
The large LCD screen displays the following information:
- IN Temperature: The temperature measured by the main unit's internal sensor.
- OUT Temperature: The temperature measured by the external waterproof probe.
- IN Humidity: The humidity measured by the main unit's internal sensor.
- Comfort Icon: Indicates the comfort level based on indoor temperature and humidity.
Button Functions:
| Button | Function |
|---|---|
| MEMORY | Press once to view the maximum (MAX) temperature and humidity recorded since the last reset. Press again to view the minimum (MIN) temperature and humidity. Press a third time to return to current readings. |
| °C/°F | Press to switch the temperature display between Celsius (°C) and Fahrenheit (°F). |
| CLEAR | While viewing MAX/MIN values, press this button to clear the recorded maximum and minimum values. The device will then start recording new MAX/MIN values from the current readings. |

Maintenance
- Cleaning: Wipe the main unit with a soft, dry cloth. Do not use abrasive cleaners or immerse the main unit in water. The probe can be wiped with a damp cloth.
- Battery Replacement: When the display becomes dim or shows an empty battery indicator, replace the AAA battery. Ensure proper polarity.
- Storage: If not in use for an extended period, remove the battery to prevent leakage and store the device in a cool, dry place.
- Probe Care: While the probe is waterproof, avoid excessive bending or pulling of the cable to prevent damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Low or dead battery; incorrect battery installation. | Replace the AAA battery, ensuring correct polarity. |
| Inaccurate readings | Probe not properly positioned; interference; device malfunction. | Ensure the probe is correctly placed. Avoid placing the unit near heat sources or direct sunlight. If issues persist, contact support. |
| MAX/MIN values not clearing | Incorrect button press sequence. | Press the MEMORY button until MAX or MIN is displayed, then press the CLEAR button. |
| Probe temperature (OUT) not displayed | Probe cable disconnected or damaged. | Check if the probe cable is securely plugged into the main unit. Inspect the cable for visible damage. If damaged, the probe may need replacement. |
