8. Address Switch
8-1. Address Setting of the Remote Control Unit
The address can be set in order to prevent interference
between remote controllers when 2 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.
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 1HR. TIMER button. Then press and hold the
ACL (Reset) button with a pointed object such as
the tip of a pen. After 5 seconds, release the ACL
button first, then release the QUIET and 1HR.
TIMER buttons. “oP-1” (Test Run) appears, blinking
in the remote controller clock display area.
(4) Each time the 1HR. TIMER button is pressed, the
display changes as shown below. Press this button
3 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) but-
ton to cancel the blinking “oP-7” display.
(Fig. 64)
Changing of the second remote controller address is
now completed.
