Funktionniert with common household current (230 V). The mitfunktionnierende knob with low voltage concerned (the button I have assembled under tension while the wire with bloßen HÃ'nden berÃ'hrt without daay nothing happened). The manufacturer recommends daay ask an electrician to install the stuff fÃ'r you. However, it is not necessary if you are not allergic to screwdrivers and drills. And else you can take a nice Nachbachn ask, even if unqualified. With only one part of the saved money you give him a bottle of champagne.
