I bought a similar item for one more, which works perfectly well, though the settings change operation. However this article, I thought was exactly the same but sold elsewhere, only on / off sensor detects nothing, the settings turn into space and endless and does not change anything because the sensor never told detected ... The adjusting screws seem much more "Camelott" than the other model ever owned ... In short, I refer and recommend another model that plugged into the same electrical test on arrival works perfectly.
