Quality poor - stay away!

Of the original 20 HR model I use throughout the house several thermostats for over 6 years, wanted to retrofit two heaters. Like the parallel purchased HR-25, which was noisy, constantly nervous nachregelte and yet did not keep the temperatures I experienced with this release an unpleasant surprise, I came yesterday in a very warm room.

The pin for valve control had broken in the wheel, shifted and became no longer regulated and down the heating powerte to full throttle. So also this botch goes back, as has been the HR 25 and I'm going to buy instead the HR 20 in the already proven design or simply cheap 15 EUR thermostat at discounters.

The here several times rightly criticized plastic connection no good at all in this version. Once the pin is dissolved therein powert the heating on full power and when you might be just on holiday, you verballert weeks insanely much energy before this misconstruction then sends back to it at least to get his money back.

Who designs the botch SO, the first time should do his homework and think!
