Can I really recommend it, very easy to use. Simply plug it in, it is immediately displayed the room temperature. Pressing on (middle button) menu is the default factory temperature of 18 degrees, easy to customize with plus or minus, and that was it. Simply interrupt with OFF. As we heat with wood, we have the thermostat in the living room in operation, because an electric heater, so the apartment is not so cool down. Works very well, clear 5 stars from me.
