We have the TTK 75 S only a short time. During this time he has withdrawn much water the air in our basement - used in three rooms. So he seems to work fine.
We complain that the TTK 75 S has no on / off switch, which completely takes the device from power - even if the power consumption by the pilot light is low - about 0.6 watts. Trotec has confirmed that in this respect the "Operating error (is) that it lights up continuously when the device is plugged in. The power can thus not be controlled." A switched outlet or a timer, we will use in future (must).
What we too much seems a little - and do not like - is elsewhere already mentioned water that accumulates below the collecting vessel and the one (actually) each would wipe / should when you emptied the tank.
The absence of other desirable settings we not rest on the device - we knew that they do not exist.
As for the service, so we hope that if we have to make use of it, it can be judged as positive, as it is written elsewhere. The previous contacts with the Trotec service do not allow for clear verdict.
With a further decision to buy a Trotec dehumidifier we would particularly draw next to the TTK 75 S TTK to 71 E and 40 E TTK in the very tight election, although these devices do not meet all needs and have weaknesses.
Buy one Trotec dehumidifier should the way as far as possible not after heavy rain periods with corresponding flood damage. During this period the prices will obviously increase dramatically so in some cases happened in 2013 and 2014 (especially in the TTK 75 S).
ADDENDUM: from even slightly below 300 over 260,61 179,95 over there's the device now for 159.72. This is 'real' market economy - financially exploit the suffering of similar by floods already enough injured.
