NOTES: 1. Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit.
2. Symbols used in wiring diagram above are. :Terminal block, :Connector, :Insertion tab.
3. Self-diagnosis function
The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch(SW1) and LED1,2
(LED indication)found on the multi-controller of the outdoor unit.
LED indication : Set all contacts of SW1 to OFF.
4. The input for CN3D 1-2(AUTO CHANGE OVER EXTERNAL SIGNEL)is as follows.
