The remote controller wire (Communication line) and AC 208 – 240V 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
