But the pre-installed cable is short and no connection to create auserhalb the radiator to ust I've the power cord from the house coming soldered directly in the housing. Unfortunately, a project which I regret, because as everyone knows thus void the warranty. After mounting Super One goes! One? and the second? No reaction. So in short the two screws on the Movement detectors dismantled and behold, a defective sensor :(. Has nothing to do with my soldering, I hät well in advance only to test. So I now have a fairly expensive radiators. From this point I'd like from the purchase advise as defective delivery to 50%. But can not prove it.
