Wired remote controller wiring
This wiring is not required when using the supplied wireless remote controller.
• For wiring remote controllers a 2 core non polarity wire must be used.
Wired remote controller wiring, remote controller inter-unit wiring
Total wire length of wired remote controller wiring and remote
controller inter-unit wiring = L + L1 + L2 + ... Ln
Total wire length of wired remote controller inter-unit wiring = L1 + L2 + ... Ln
• The remote controller wire (Communication line) and AC 220V 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
specifi cations and maximum number of connectable indoor units will be changed. Pay attentions to
their communication specifi cations when carrying out the installation, maintenance, or repair.
For its details, refer to the "Communication line" in 10 Electrical connection.
