<In the case of combining with outdoor units of Super Modular Multi System u series (SMMS-u)>
Uv line and Uc line (L2, L3, L4)
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
(L3+L4) in each refrigerant line is up to 3280'10"(1000 m)
* Even if the indoor unit and the remote controller are "other than U series", the wiring
specification are the same.

• The length of the communication line (L1+L2+L3) means the total length of the inter-unit wire length
between indoor and outdoor units added with the central control system wire length.
* Even if the indoor unit and the remote controller are "other than U series", the wiring
specification are the same.
