Have simple requirements for this specimen, the TTK 75 to a basement room dehumidification. For this, he runs every day a few hours on a timer. It is positive that the settings are saved on the device, because there are mechanical switches and knobs. Actually, everything works, the humidity is reduced - only this drawer is the last: Single Wall made of hard plastic, never goes out or purely on a train, stuck in principle and then really, when the drawer is full; she has to even the slightest material appearance. Cancels here from what - and this is already threatening if one spends a little more power - I can certainly forget the device completely, although it would probably still running. A real nuisance. I still have the TTK 70 for the apartment, that's better. For this you can this back not to operate a timer because electronic keys. Another disadvantage of the TTK 75 is that the compressor can not be switched on permanently - even in the "min" level turns off the dehumidification when "the device keeps the humidity low for". This results in a humidity meter elsewhere in the space indicating just below 70%, the TTK 75 but does not turn on.
From my perspective, the TTK 75 is recommended only limited, also because there is just a large number of other devices. Purchase date was November 2012 Design.
