The terminal S on the terminal block (TB7) for the central control panel should be connected to the ground terminal
components box for one heat source unit only.
•
Never connect together the terminal blocks (TB5) for transmission wires for indoor units (IC) that have been connected to different heat
source units (OC).
•
Set all addresses to ensure that they are not overlapped.
