The FSU acquires power monitoring information through RS485 port, and uploads information of components such
as heat exchanger and air conditioner through internal RS485 port. The FSU universally processes and transmits the
information to user monitoring system through Ethernet remote communication port. The appearance and port
position of the FSU are shown in Figure 1-15.
