1. Terminal numbers of outdoor and indoor units must be 

matched.

2-1. Connect the remote controller only to the master unit.
2-2. The remote controller needs to be wired only to the mas-

ter unit; it does not need to be connected to the slave 
units through transition wiring. (Do not connect transition 
wiring to the slave units.)

2-3. The indoor temperature sensor is effective only for indoor 

units to which the remote controller is connected.

2-4. The length of wiring between the indoor unit and the out-

door unit varies depending on the connected model, the 
number of connected units, and the maximum piping 
length.
For details, refer to the technical documents.

NOTE

• Terminal numbers of outdoor and indoor units must be 

matched.

When implementing group control

• When using as a pair unit or as a master unit for simultane-

ous operation system, you may carry out simultaneous start/
stop (group) control up to 16 units with the remote controller. 
(Refer to Fig. 34)

• In this case, all the indoor units in the group will operate in 

accordance with the group control remote controller.

• Select a remote controller which matches as many of the 

functions (airflow direction, etc.) in the group as possible.

Wiring Method

(1) Remove the control box cover. (Refer to ‘‘9. HOW TO CON-

NECT WIRINGS AND WIRING EXAMPLE’’.)

(2) Connect crossover wiring between the terminals (P1, P2) 

inside the control box for the remote controller. (There is no 
polarity.) (Refer to Fig. 34 and Table 3)

Two remote controllers control (Controlling 1 indoor unit 
by 2 remote controllers)

• When using 2 remote controllers, one must be set to “MAIN” 

and the other to “SUB”.

MAIN/SUB CHANGEOVER

• Refer to the manual attached to the remote controller.

Wiring Method

(1) Remove the control box cover.
(2) Add wiring between the remote controller 2 (Sub) and the 

terminal (P1, P2) of the terminal block (X1M) for the remote 
controller in the control box. (There is no polarity.)
