Hello There. I have after much back and forth I decided on this thermostat to our underfloor heating in the living room to control a trial basis. I find the thermostat by 3 Wochigen now use super convenient that I have now ordered extra for our kids 2. Simply eingbaut, 3 cable connected, fuse pure, programmed and ready. The documentary is not quite logical - or simply play around with it, however, is not a problem because it is not really complicated. You can even adjust the preset temperature sensor. So I have a Thermomether I trust placed next - and set the temperature at this. Can it therefore highly recommend and it also looks very chic,
