Why is the temperature displayed on my humidor lower than the set temperature?

Why is the temperature displayed on my humidor lower than the set temperature?

Please don't worry, this is not a malfunction. This is a normal phenomenon for products using semiconductor refrigeration technology.
1. Our product only has cooling function, so it is normal for a temperature difference of 2-3℃ under different circumstances.
2. After setting the temperature, it is recommended to close the door of the humidor and let the fan work. During this period, please do not open the door frequently to keep the temperature inside the box stable.
3. Maybe you could also turn the temperature up a bit (no more than the ambient temperature) and see if the temperature inside the humidor rises.
