● Link wiring
N OT E
● A terminal plug (black) is attached to each of the outdoor unit
control PCBs. At only 1 outdoor unit, leave the terminal plug
short-circuit socket on the "Yes" side. At all the other outdoor
units, change the socket (from "Yes" to "No").
● A maximum of 8 indoor units can be connected to 1 remote
controller for group control.
* If wall-mounted type units are used for a simultaneous-operation
multi system (group control), refer to 10-16. System Control
(basic wiring diagrams and wiring procedures) when wiring.
