A load control system may include control-target devices, control-source devices, and a system controller. The control-target devices may enter an association mode to associate with control-source devices. The control-target device may receive an identifier from the control-source device and store the identifier in memory when the control-target device to associate the control-target device and the control-source device. The system controller may retrieve the association information from the control-target device after integration into the load control system. The system controller may receive association information that is defined using other association procedures, such as an association procedure performed on a network device and uploaded to the system controller. The system controller may maintain the association information defined using the different association procedures after the system controller is integrated into the load control system. The system controller may also maintain control configuration information configured prior to integration of the system controller.
