I ordered this Heizkörperthemostate after I made abysmal experience with the Set of Casa Control Smart home systems Starter Set Premium. These thermostats were doing what they wanted, never kept the temperature, were very loud in the regulation of flow temperature and five out of eight were simply over after four weeks! The HomeMatic thermostat I took the second attempt after six weeks and am more than impressed! All thermostats are working properly! The setting of several thermostats for each room needs a few minutes and careful reading of the manual, but then all is well! The thermostats are almost silent in control! The temperature can be changed directly on the thermostat and it works! No matter what as Wi-Fi in the control software - has set the way, also works flawlessly and driving smoothly in all rooms Wi-Fi .... who surrounded by hand, experienced that the thermostat regulates within 60 seconds! And not only that! I have rooms with three thermostats ... I put a, the other also react immediately and choose to have the same temperature! Once interconnected, the control is working properly! A radiator changed, the others are synced within 60 seconds ... Technology that inspires. Also pleasant, the control system with digital display is illuminated, so you can even in dark corners without problems regulate the temperature. Also helpful: the temperature control via EQ3 HomeMatic wireless wall thermostat 132030 also works flawlessly! In two rooms I have several radiators which are operated centrally via the controller. Again, the control works well, with the only restriction that the wall thermostat is not illuminated. Only thing missing is the programming of the app for the iPhone that comes in a few days ... However, I am optimistic that this app AOES Fernartung works just like the equipment on site in the WLAN does. After six weeks of practice text ... absolute buy recommendation for this digital radiator regulation that ... simply ... work! Unrestricted buy recommendation!
