Communication wire
Remote controller wiring
On the outside of the unit, do not allow the wire for the remote controller (communication wire) and the wire for AC220-240V to come into contact
or put them together in one electrical conduit; otherwise, the control system may have trouble due to noise.
* The total length of the remote controller inter-unit wiring is the same for both between the indoor units and
between the Air to Air Heat Exchanger.
