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.

1.If the wire diameter is enlarged to 2×1
mm² (2×AWG16), the total
communication line length can reach
1500 m (4921-1/4feet).
2.The cord shall be Circular cord (the
cores shall be twisted together).
3.If unit is installed in places with
intense magnetic field or strong
interference, it is necessary to use
shielded wire.
