The switches offer a number of possible settings, however the service after studying the brief instructions and once practice is relatively easy. However, one should keep the manual well, as the menus are displayed only by code "H1", "H2", etc.! More is certainly not to be expected with the display.
I now use the automatic startup and shutdown with Astro function, ie using the country specified white switch sunrise and sunset. Otherwise, times for each day can be set individually, there is a random function (+/- 15 minutes) and you can loop through signals to a central controller. In addition, an optional sun sensor can be connected.
Only serious criticism deserves the wire tie at the bottom. Thus, the cables must be unbent directly to the terminal, to accomplish impossible with cable lugs. Here is an attachment directly to the back along with a deep flush-mounted box would certainly be the best option.
But for my upstairs I'll use these switches in the renovation next year certainly again.
