Had bought a few months ago this switch, because I wanted to switch off especially in the bathroom on our Beuler After (although one should not really, but what is already great pass at nem cheap device of Beuler ...). I am very pleasantly surprised in fact, because the device already works great and can be adjusted relatively well. There are only two small things that bother me: (1) The machine does not automatically switch from summer to winter time and vice versa, but it has only one button for it to (you have it so even trigger). And it is commendable at least once before, that this feature has been taken up in principle! (2) The setting is not really possible without rumprobieren after a few months so without manual or (alternatively). While the buttons are well labeled and designated extent, but it is always such a thing, the mode I've just selected ...
Basically, so everything here as promised, you can also a lot of combinations and switching options to select, but the operation and the handling with summer / winter time could be a bit better.
