I had issue with dryer on this unit, so replaced photo sensor but some how managed to loose the configuration sheet i made before i went crazy on the multiplexer. Everything else works fine besides dryer not contouring. Maybe someone can help me with DIP settings on top of multiplexer. I have three sensor on dryer on both sides two transmitter and one reciever on one side and opposite the other side. im in countryside and there is no help out here but this forum. Hopefully someone can help me or point me to right direction. A manual would be a plus if i can get one. thanks.
