(3) Serial Communication Error Identification Procedure

Refer to "Method of Self-Diagnostics" for the self-diagnostics procedure.

(3-1) Condition: E01

< Before the Operation >

If the lamps on the main body show the following conditions after the completion of self-diagnostics,

a communication error between the indoor unit and outdoor unit might be considered.

In such a case, identify the breakdown section by using the following procedure.

Troubleshooting Serial Communication

Is the voltage of about DC12V

or more given between the terminals

2 and 3 on the outdoor unit terminal strip

(Serial Communication Line) ?

(Fig. 1)

Yes

1. Turn OFF the power and wait until the power lamp (LED)

 of the outdoor unit controller is turned OFF.

2. Disconnect the cable from the terminal 3 on the indoor unit

 terminal strip. (Fig. 2)

3. Turn ON the power.

< Convenient Tool for Short-Circuit Work ( for example ) >

Alligator Clip

Cable

( Continued to the next page A. )

( Continued to the next page B. )

For terminal strip short circuit work or inter-unit wiring removal, turn off the power to

avoid an electric shock.

Release the terminal strip short circuit after the completion of self-diagnostics.

Do not perform the short-circuit work between any other terminals except for

specified ones on the specified terminal strip. If such work is performed between

the incorrect terminals, the unit might be broken.
