We have the power now for over 3 weeks our cellar in use and are very pleased with the Entfeuchterwirkung. Small, compact, quiet and very efficient. I have now mounted a drain hose because I previously had 2 x per day to empty the tank. Before the unit was set up, I have set up to compare a measuring device; from an initial 84% humidity was suppressed to 67%. But the unit also runs then almost continuously. Therefore, the have the setpoint now set at 65%. And here is where my only minor complaint. The setpoint can be adjusted only in steps of 5. At 60% setting, the unit runs continuously, at 65%, it will turn off in the meantime, if the default value has been reached. What is also beneficial for lower power consumption, of course. From my perspective, unlimited purchase recommendation.
