Change the value in SET DATA to that of a new address.

5 Push the SET button to confirm the new address on SET DATA.

6 Push the button (left side of the button) repeatedly to select another address to change. Each time you push the button, the indoor unit numbers in a refrigerant line are indicated one after another. Only the fan and louvers of the selected indoor unit are activated.

Repeat steps 4 to 6 to change the indoor unit addresses so as to make each of them unique.

7 Push the SET button.

(All the segments on the LCD display light up.)

8 Push the TEST button to finish the procedure.

4 After a time “U.1.L08” appears on the 7-segment display if the address clearing has been completed successfully.

If the 7-segment display indicates “A.d. n.G.”, the outdoor unit may still connected with other refrigerant lines. Check the connection of the relay connectors between [U1, U2] and [U3, U4].

NOTE

Take care to carry out the procedure above correctly; otherwise, addresses in other refrigerate lines may also be cleared.

5 Set the addresses again after finishing the clearance.
