(1)Refer to Section 5-2. “Recommended Wire Length and Wire Diameter for Power Supply System” for the explanation of “A,” “B,” “C,” “D,” and “E,” in the above diagram.

(2)The basic connection diagram of the indoor unit shows the 7P terminal board, so the terminal boards in your equipment may differ from the diagram.

(3)Refrigerant Circuit (R.C.) address should be set before turning the power on.

(4)Regarding the R.C. address setting, refer to page 72. Auto. address setting can be executed by remote controller automatically.

Refer to page 72 – 76.
