I have installed this Rollladenmotor for my defective, also of Rademacher, built (Werufenster-) Rollladenmotor the 4000 series. After initial difficulties (another engine mounts necessary) I can solve the problem with an adapter plate of the very good advice by telephone from BRR Exactus GmbH (Amazon traders) and of Rademacher himself. The installation itself and the setting of the end points was simple. Since I had a remote control Easy Standard "only", I had to set the endpoints with the reset button on the engine itself. But worked without problems. During operation of the assembly and flow was then reversed, but using the technique of Rademacher also this problem could be solved. My first engine stopped 5 years. Warranty period were 36 months. The new engine has a warranty of 10 years. Am curious .... So far, I can recommend a motor of the company. Rademacher, solely because of the good service. But I'm assuming that motors from other manufacturers, according to today's standards, easy to install and adjust easily are.
