The idea of a connected smartphone thermostat I found interesting. Until now I always have to change a setting in the basement room. So I bought myself the thermostat and am super happy! I was just not sure in the beginning if my boiler is compatible, however, is an online check on the home ready. The installation was quick and easy to create with the German online video. The programming via the app is flawless and user-friendly. The adjustment of the program to outside temperature and insulation is awesome especially in the autumn months.
