Operating Instructions
Display Overview
The LCD screen displays indoor temperature, and temperatures from Sensor 1 and Sensor 2 simultaneously.

Image: The clear LCD provides real-time temperature readings for indoor, Sensor 1, and Sensor 2, along with maximum and minimum recorded temperatures.
Temperature Unit Selection (°C/°F)
Press the "+/°C/°F" button on the main unit to switch between Celsius and Fahrenheit display.
Max/Min Temperature Records
The main unit automatically records the maximum and minimum temperatures for indoor, Sensor 1, and Sensor 2 over a 24-hour period.

Troubleshooting
| Problem | Solution |
|---|---|
| Screen does not display content. | Check battery installation and ensure the transmitter is connected to the host unit. Replace batteries if necessary. |
| Inaccurate temperature readings. | Ensure new batteries are installed. Verify sensors are placed correctly and not exposed to extreme conditions beyond their operating range. |
| Multiple sets interfering. | If you have two sets, install one completely and ensure it's connected firmly before installing the second set. This helps prevent signal conflicts. |
| Alarm not activating immediately. | The alarm function has a 10-minute delay after activation to prevent false alarms from temporary door openings. |
| Max/Min data not updating. | The Max/Min data updates every 24 hours. Press the "CLEAR" button to reset and start a new 24-hour cycle. The product does not support viewing all previously recorded temperatures. |
