<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.

CAUTION
• The remote controller wire (Communication line) and AC 208/230V wires cannot be parallel to contact
each other and cannot be stored in the same conduits. If doing so, it may cause troubles on the control
system due to noise or other factor.
• If U series models (TU2C-Link) are combined with models other than U series (TCC-Link), the wiring
specifications and maximum number of connectable indoor units will be changed. Pay attentions to their
communication specifications when carrying out the installation, maintenance, or repair For its details, refer to
the "Communication line" in 8 Electrical connection.
