Wire size :
(2-core shield wire, non-polarity)
Uh line (L1)
Wire size :
(2-core shield wire, non-polarity)
• U (v, h, c) line means of control wiring.
Uv line : Between indoor and outdoor units.
Uh line : Central control line.
Uc line : Between outdoor and outdoor units.
Uv line and Uc line are independent from another refrigerant line. Total length of Uv and Uc lines
