Power supply
Control wiring, Central controller wiring
2-core with polarity wires are used for the Control wiring between indoor unit and outdoor unit and Central
controller wiring.
To prevent noise trouble, use 2-core shield wire.
The length of the communication line means the total length of the inter-unit wire length between indoor and
outdoor units added with the central control system wire length.
Power supply
220-240V ~, 50 Hz
Power supply switch / circuit breaker or power supply wiring / fuse rating for indoor units should be selected by the
accumulated total current values of the indoor units.
