After installing the device, I naturally looked the same after an update of the FW and install this.
So then you could see the language (in addition to the previous: English + Polish) also convert German.
I (Danfoss Living Connect thermostats) this language setting but again changed during the installation of the first 3 Z-Wave devices in English, the translation into German is just too bad and confused more than it explains.
Currently we have incorporated 3 thermometer on the network and hope through the "smart home" a reduction in heating costs in the coming heating season.
Although these 3 thermometers have a thermometer, but as this is located directly on the heat source ...
Ergo: the controller & 3 x Danfoss Living Connect was a start, that's all.
