Specifications for communication wiring
◆Design of communication wiring
Summary of communication wiring
• Communication wiring and central control wiring use 2-core non-polarity wires.
Use 2-core shield wires to prevent noise trouble.
In this case, for the system grounding, close (connect) the end of shield wires, and isolate the end of terminal.
Perform the ground of wires at one side only for the header outdoor unit.
• Use 2-core non-polarity wire for remote controller. (A, B terminals)
Use 2-core non-polarity wire for wiring of group control. (A, B terminals)
