This means that condensation dehumidifying (cold plate against hot air), so really effective beyond 15 ° C (even if the hot air function to defrost the plate).
If that's still a cellar below 15 ° c, prefer a dehumidifier with silica gel, it will be much more efficient and profitable.
This dehumidifier stops completely once the relative humidity reached Importantly, because many have the fan running continuously (see Delonghi available at casto or Leroy-Merlin, so unbearable noise).
Powerful but very noisy, ok for a basement, not for a living.
The failure of this product: unreliable at all, broken (compressor HS) after 18 months, this kind of compressor (same as the refrigerator must hold at least 5 years or even 10)
Other default, a button (control wheel without graduation).
So without a hygrometer next, no chance to adjust fairly well.
I do not recommend this product, too fragile.
