<In the case of combining with outdoor units other than Super Modular Multi System u series (SMMS-u)>
Control wiring between indoor units, and outdoor unit (L2, L3)
(2-core shield wire, non-polarity)
Central control line wiring (L1)
(2-core shield wire, non-polarity)
Control wiring between outdoor units (L4)
(2-core shield wire, non-polarity)
• 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.
