The number of 

connected

outdoor units is 

too few.

Miswiring of communication lines between outdoor units 
or an unconnected wire ( Fig. 4). (Address setup 
operation finished without recognizing a miswired 
follower unit.)

After modification of wiring, set up the addresses again and 
check the number of connected outdoor units.

The number of 

connected indoor 

units is too few.

Miswiring of communication lines between indoor units 
or an unconnected wire ( Fig. 5). (Address setup 
operation finished without recognizing a miswired indoor 
unit.)

After modification of wiring, set up the addresses again and 
check the number of connected indoor units.

The number of 

outdoor units 

connected to a 

group is too few in 

group operation 

from an indoor 

remote controller.

The indoor remote controller is not connected with wire.
Miswiring of the indoor remote controller

Using the main indoor remote controller connected to a group, 
start a test operation, specify the unit that is not operating (the 
unit not connected to the group), and then check the wiring.

Indoor remote controller communication circuit error
If 220-240 V is incorrectly applied to the remote controller 
terminal, the remote controller communication circuit 
fails.

Using the main indoor remote controller connected to a group, 
start a test operation and then specify the unit that is not 
operating (the unit not connected to the group). Remove the 
fast-on terminal connected to remote controller terminals A/B, 
and check the voltage. If voltage is not applied (normally 15 
to18 V), replace the PC board.
