10-2 CONTROL BY 2 REMOTE CONTROLLERS (Con-

trolling 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

(1) Insert a 

 screwdriver into the recess between the 

upper and lower part of remote controller and, working 
from the 2 positions, pry off the upper part.

The remote controller PC board is attached to the upper 
part of remote controller.

(2) Turn the MAIN/SUB changeover switch on one of the 

two remote controller PC boards to “S”.

(Leave the switch of the other remote controller set to “M”.)

Wiring Method

 (See ‘‘9 ELECTRIC WIRING WORK’’)

(3) Remove the control box lid.

(4) Add remote controller 2 (SUB) to the terminal block for 

remote controller (P

1

, P

2

) in the control box. 

(There is no polarity.)

[ PRECAUTIONS ]

Crossover wiring is needed when using group control and 
2 remote controllers at the same time. 

Connect the indoor unit at the end of the crossover wire 
(P

1

, P

2

) to remote controller 2 (SUB).

10-3 REMOTE CONTROL (FORCED OFF AND ON/

OFF OPERATION)

Connect input lines from the outside to the terminals T

1

 

and T

2

 on the terminal block (6P) for remote controller to 

achieve remote control.

See the “

11. FIELD SETTING AND TEST RUN”

 for 

details on operation.

10-4 CENTRALIZED CONTROL 

For centralized control, it is necessary to designate the group 
No. For details, refer to the manual of each optional control-
lers for centralized control.

11. FIELD SETTING AND TEST RUN

〈〈〈〈

Field settings may have to be performed using the 

remote controller, depending on the type of installa-

tion.

〉〉〉〉

(1) Make sure the control box lids are closed on the indoor 

and outdoor units.

(2) Depending on the type of installation, make the field 

settings from the remote controller after the power is 
turned on, following the “Field Settings” manual which 
came with the remote controller.

The settings can select “Mode No.”, “FIRST CODE NO.” 
and “SECOND CODE NO.”.

The “Field Settings” included with the remote controller 
lists the order of the settings and method of operation.

Lastly, make sure the customer keeps the “Field Settings” 
manual, along with the operating manual, in a safe place.
