As the products of Shina System are designed to be versatile systems from the development phase, they can be integrated at the level of the DDC communication line such as LCU-2000, a lighting controller, and FCU-2000, a DDC for equipment/power control. It means smooth control of interoperation through perfect integration of each system, and the advantages of true integration of the BAS system can be maximized as universal software and hardware of other companies can be integrated and applied like one of the parts of the Shina System, if required later.
