Why doesn't ROHAN's fan stop in automatic mode?

The ROHAN dehumidifier works with R290 gas, as required by the European Union from 2021, for all devices containing a refrigerant gas.

As specified in the user manual, when you program your device to reach a certain humidity level and this level is reached, the compressor stops and only the fan continues to operate.

This is completely normal and complies with a European safety standard (EN 60335-2-40 concerning "Household electrical appliances and analogues - Safety - Part 2-40: Special requirements for electric heat pumps, air conditioners and dehumidifiers").

If you want your appliance to turn off completely, you can turn it off manually or via the smartphone app, or set a timer.
