How do I add another control to my programmed Somfy product?

Adding a new control is easy. Start with the control that operates the shade. If using a multi-channel control, select the channel that operates the shade. Press and hold the program button on the back of the remote until the shade jogs. Then, move to the control to add and select the channel (if applicable). Press and release the program button on the new controller and the shade will jog. A new control has been added.
