Received the engine very quickly, well packaged in a cardboard protected by a "card mulching", there was also an installation manual. I installed the engine on the shutter, compatibility is actually perfect, for against a problem has occurred in the remote setup, following the instructions the direction of rotation was reversed, having struggled a bit, I found the solution on the forum SOMFY through a video that describes the manipulation step, in fact at one stage leaflet said support 0.5 sec off is 7 sec. Here everything is back to normal and the flap is repaired (the video is on YT). good transaction, thank you also for putting SOMFY online tools like this very useful video.
