2.4 Communication cable and control cable

Note: For air conditioning units installed in places with strong electromagnetic interference, shielded
wire must be used as the communication cables of the IDU and wired controller, and shielded twisted
pairs must be used as the communication cables between IDUs and between the IDU and ODU.
