I also have this problem. I called Horizon and they said to follow the detailed instructions for programming the 7102 (link below).

But I cannot get it to work exactly right. The flap up switch works, as does the middle switch position for flaps down. However, the flap switch down position only causes my ailerons to deflect up a little, while the flaps go completely down. This causes a lift effect. When I increase the offset as the instructions say to increase aileron throw, the offset creates a slight offset in the flap up or flap middle switch position (which is a problem). So I am unable to increase the aileron up throw. I hope I explained that correctly.
