(*2) (*3)
• 2-core with non-polarity wires are used for the Indoor / Outdoor inter-unit wiring 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.
(*4)
• 2-core with non-polarity wire is used for wiring of the remote controller wiring and group remote controllers wiring.
Remote controller wiring, remote controller inter-unit wiring
Total wire length of remote controller wiring and remote
controller inter-unit wiring = L + L1 + L2 + ··· Ln
Total wire length of remote controller inter-unit wiring = L1 + L2 + ··· Ln

On the outside of the unit, do not allow the wire for the remote controller (communication wire) and the wire for
AC220-240 V to come into contact or put them together in one electrical conduit; otherwise, the control system may
have trouble due to noise.

5. Using a no voltage a-contact input of the external input (sold separately), the following operations are available:
Between 1 and 2: Selecting the remote controller operation (Invalid / Valid)
Between 1 and 3: Adjusting the fan speed (Low / High)
Between 1 and 5: Operation (ON/OFF)
Use a microcurrent contact (DC12 V, 1 mA). In addition, ON/OFF operation is possible when using a voltage of
DC12 V or 24 V.
6. Orange wire (High) is connected as factory default. To switch to "Extra High", connect black wire's connector
instead of orange.
7. The unit cannot run when the temperature of the outdoor air is below -15 °C.
