The only drawback I would like to add that a point in the description of missing something, or is poorly presented. If I set up my thermostat 21 degrees then it controls the heating precisely 21 degrees out but unfortunately only in the place where the thermostat is installed and that's usually next to the radiator, where it's a bit warmer than in the rest of the space. For this purpose, can be in the software, an offset adjust temperature, at least in a small control range. I would have helped if they would have been described in the manual.
I'm going to now additionally the wall thermostat buy hope to achieve even tighter control.
Otherwise I can only recommend the thermostat!
