We considered long if it makes sense zuzulegen us a programmable radiator controller but in the end I have but then decided to do it and I have from the very beginning for a second regret this purchase. After unpacking the batteries (not included) are inserted and the machine began to "live". After the firmware has been briefly displayed, date and time had to be set. This was no problem hinzubekommen without the manual to read. Once the settings have been made could be put on the Rondostat on the radiator and the unit has adjusted directly without my help. After about 30 second, the unit has been in operation and ensured that the room was heated to the set temperature. After a brief look at the manual, I then made me turn the heating times for programming and also this was super easy! You can set two Heizzeitenintervalle or to provide up to two heating period for each day of the week either for the whole week. Really super. I have it programmed the heating half an hour before we starts coming home, thus we always have a nice pleasant heated living room and do not have to even freeze until the room is warm. The risk that forgot to turn off the heater when we go to bed we is eliminated with the programming. Another advantage is that recognizes the Rondostat whether the window is open or not. Because as soon as the thermostat a larger temperature drop registered, it turns off the heating and only in when the window was closed again. The set room temperature is distributed also to the entire space. This I have checked with a thermometer at the other end of the living room. Of course you can adjust the thermostat with only one push of a button to manual operation, so that you always have its desired temperature in its premises!
Conclusion: The machine is very reliable and also the room temperature is distributed in the entire room. We do not want to miss these little helpers for everyday use and are of the firm belief that we will thereby reduce our next fuel bill with security.
