This Vestamatic timer from Jarolift in execution "Multi-Time Control" controls our shutters (as have them bought some) time. There is quite a difference whether one day two or more times, depending on the sunlight, the roller shutters up and down moves or "fall" leaves. The time switch together with the tubular motor is an extremely practical tool in the daily routine. Particularly noteworthy is the sun automatic with any configurable sensor at the window. Just great! Especially my wife does not want to miss this technique (with electronics). No reference material of the upholstered furniture and no window sill flower burns now more in the sun. Not to mention the leave or variable circuit. In our absence the potential thieves have problems. So we feel more secure. All in all: The best solution, since there are windows shading.
