Abnormal operation.

After the part is now at parties than IQ test. Who gets to boil the water, in what time?

You have to press the part with the "ON" switch. => It is the current temperature of the water is time, therefore, for example. From the hot water tap 55 °.
Then press the up arrow key once, so that it indicates 100 °.
Then down with the arrow go to the desired temperature (unless one of boiling water, but eg. 85 ° will have for green tea, like me, mostly), and it happens ... nothing.
Because then you have only once more to the "ON" button switch, so that it starts.

But this one's right puzzled, then the unit does not show after another click on "ON" the just EINGESTELTE temperature (although this is in fact still valid), but jumps back (which then rises slowly) to the measured display of actually just current temperature.
One can rely on the matter but, it will reach the two steps previously set temperature.

By contrast, completely unnecessary, annoying ° C / ° F Shift hardly matters (you really have to produce one unit for EU and USA? No, do not have to, I think).

Well, if you get it's only once (I have deliberately accumulate his wife and son and me royally amused - three technically quite gifted who once failed), it's off, so keep with grumbling, otherwise OK.

But the designer belongs powdered with the staple bag.
