If you still have to open and close your shutters manually using a belt, this video is for you. We show you how to remove a manual belt winder and replace it with an electric belt winder. In this video, we use the top model, the RolloTron Comfort DuoFern 1800. In addition to the automatic program, the integrated radio receiver is particularly interesting, because it allows the device to be operated by handheld transmitter, smoke detector, smartphone and voice control (Alexa and Google).
