rather primitive

I had a ELRO bought and installed VD64 Videophone some time ago and am satisfied with the quality. To replace the existing door opener I then ordered my BD5005L. That the only has a simple sword and has no angled and no mechanical release was seen in the product description. However, I was disappointed because the housing was significantly greater than that of a normal opener, I had it widen the opening in the doorframe. Another shortcoming is the primitive processing with a aufgeklippsten plate cover, and the lack of adjustment of the distance of the opening bar. So real scrap.
I now have the old door opener (more current needs) first used again, you have now a couple of times or press and hold until the door opens. I'll probably leave the old opener inside and controlled via a relay with 12V, 1A, the VD64 switches only the relay.
