TRANSMISSION WIRES DC12V

 

NOTES:

 

 

 

 

1. Symbols used in wiring diagram above are,

: Connector,

: Terminal (block).

 

2.Indoor and outdoor connecting wires have polarities, make sure to match terminal numbers (S1, S2, S3) for correct wirings.

3.Since the outdoor side electric wiring may change, be sure to check the outdoor unit electric wiring diagram for servicing.

4.This diagram shows the wiring of Indoor and Outdoor connecting wires (specification of 230V), adopting superimposed system of power and signal.

w1. Use copper supply wires.

[Self-diagnosis]

1.For details on how to operate self-diagnosis with the wireless remote control, refer to the technical manuals etc.

2.For the wired remote control : When you quickly press twice the CHECK switch on the remote control, the unit begins self-diagnosis, and Check Codes generated in the past appear on the display.

For check Codes and Symptoms refer to the table below.
