12. MAINTENANCE
12-1. Address Setting of the Remote Control Unit
The address can be set in order to prevent
interference between remote controllers when two
indoor units are installed near each other. The address
is normally set to "A." To set a different address, it is
necessary to change the address on the second
remote controller.
NOTE
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. 1). When the tab is removed, the address is
automatically set to B (Fig. 2).
(3) Press and hold the remote controller ION 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
button once to change the display to "oP-7"
(address setting). (Fig. 3)

(5) "oP-7" has now been selected for address setting.
(6) Press the ON/OFF operation button on the remote
controller. (Fig. 3) 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.

Changing of the second remote controller address is
