Only two adjustable temperatures

Even the photo is misleading, 19.8 degrees can not adjust to only 0.5 degree steps. Regardless, even enough. Disappointing is that you can set only two temperatures, comfort temperature or saving temperature. This was the predecessor model differently !! In the previous one could, for each time phase set a temperature, not now. Why this is different now I do not understand. Otherwise, the device works great! At the very beginning it calibrates itself to the heating valve and can thus control the temperature accurately. You have to adjust the offset temperature right but only before the space is actually brought to the set temperature on the thermostat. It helps a thermometer to make the middle of the room for adjusting the temperature. Overall a good and inexpensive device !! The previous model I use for two years.
