Matt973 years ago000Is the set according to the photos? A "control unit" and 3 heating controllers? Or just the three thermostats?Show in original language (German)ks.geissbuehler3 years ago+110 Helpful answerExactly: control unit + 3 controllers. What I hadn't considered myself: the control unit contains no operating elements, is simply plugged in and controls the whole thing. It is operated exclusively via the app.Show in original language (German)Comment1 comment
