Max. 200 m (656 ft)
Remarks
The maximum allowable length of transmission cables via outdoor units (both centralized control transmission cables
and indoor-outdoor transmission cables) is 500 m (1640 ft)
*1
.
The maximum allowable length of transmission cables from the power supply unit to each outdoor unit or to the system
controller is 200 m (656 ft).
* Do not use a single multiple-core cable to connect indoor units that belong to different refrigerant systems. The use of a multiple-core cable
may result in signal transmission errors and malfunctions.
* Ensure shield continuity when extending the transmission cable.
*1 When extending the length of the transmission cables to 1000 m (3280 ft), consult your dealer.
