After moving we decided again for electrically Gurtwickler. In particular, the timing is not just a holiday, but also if it at night (in the absence of) times a little later, is of advantage. Design, installation, programming, everything solved well. However, what really bothers me somewhat, is the time offset of two simultaneously programmed devices in a room, which adds up, and amounts per week about 1min. Why not full marks. For this purpose it should be said that the winders operate very quietly. Conclusion, largely recommended.
