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.

Remote control wiring
2-core with non-polarity wire is used for wiring of the remote control wiring and group remote controls wiring.
Remote control wiring, remote control inter-unit wiring
Total wire length of remote control wiring and remote
control inter-unit wiring = L + L1 + L2 + ... Ln
Total wire length of remote control inter-unit wiring = L1 + L2 + ... Ln
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, a trouble may be caused 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.
