The fan always runs !!!

The device was thought to myself by a small basement room of 10m ^ 2 to keep low humidity.
For this purpose the device should automatically switch off when reaching the desired dryness and automatically on again.

That is exactly what this device does not!
The fan is always running. Only the drying portion switches off.

I suspect the reason in the other reviews complained in constant Turn on and off due to the bad-placed sensor. This is with this circuit though certainly avoided, but is also determined better.

That is an absolute indictment of technical competence.
Although the unit will make a good impression.

The question whether the classification efficiency is at all correct.

The unit returns.
