8. Address Switch

8-1. Address Setting of the Remote Control Unit

The address can be set in order to prevent interfer-

ence between remote controllers when two indoor

units are installed near each other. The address is nor-

mally set to “A.” To set a different address, it is neces-

sary to change the address on the second remote

controller.

Once changed, you cannot restore the original

address setting of the air conditioner.

(1) Switch on the power source.

(2) Break the address-setting tab marked “A” on the

second remote controller to change the address

(Fig. 62). When the tab is removed, the address is

automatically set to B (Fig. 63).

(3) Press and hold the remote controller QUIET button

and 1 HR TIMER button. At the same time, press

the ACL(reset) button. Use a thin object such as

the tip of a pen to press the ACL button. When this

has been done, “oP-1” (test run) appears, blinking,

in the remote controller clock display area.

(4) Each time the 1 HR TIMER button is pressed, the

display changes as shown below. Press this but-

ton 2 times to change the display to “oP-7”

(address setting). (Fig. 64)

(5) “oP-7” has now been selected for address setting.

(6) Press the ON/OFF operation button on the remote

controller. (Fig. 64) Check that the “beep”signal-

received sound is heard from the second indoor

unit (approximately 5 times). The sound you hear

is the signal that the remote controller address

has been changed.

(7) Finally press the remote controller ACL (reset)

button to cancel the blinking “oP-7” display.

(Fig. 64)

Changing of the second remote controller address is

now completed.
