Is the number of

connected indoor units up

to 128 units?

Is the different

address No. assigned to each

indoor unit?

Is E2 displayed?

Reset the power supply and restart.

Caution:

Unless the power

supply is reset,

addresses will not

be confirmed.

YES

Review number of

connected units.

Correct indoor unit address

setting.

Implement test run.

Replace indoor control

PCB. *

* Before replacement,

confirm whether the

rotary switch for address

setting is not damaged. (It

was experienced that No.

5 on rotary switch was

not recognized.)

2. Error detection method

More than 129 indoor units are

connected in the same superlink

system.

Duplicated indoor unit address

3. Condition of error displayed

Same as above

4. Presumable cause

• Number of connected indoor

units exceeds the limitation.

• Duplicated indoor unit address

• Indoor control PCB anomaly
