The Tastor Mercato SD-Astro impresses primarily with its user-friendliness and simple setup. The desired switching times can either be set via the menu or easily stored using the memory function by pressing the respective direction button for 6 seconds. The adjustable astro time ensures that the hassle of changing switching times is a thing of the past. The operation is very logically structured and quick for anyone to learn. The activatable random function shifts the stored switching times by 1 to 31 minutes to create the illusion of presence. Thanks to the 50 x 50 mm Plexiglas cover, the Tastor Mercato blends better than other timers into almost all common switch programs, as the minimally different shades of white are no longer noticeable.
