7-1. 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.
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. 13). When the tab is removed, the adress is
automatically set to B (Fig. 14).
(3) Press and hold the remote controller ION button
and 1 HR 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 ACL
button first, then release ION and 1 HR TIMER
buttons, "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 2 times to change the display to "oP-7"
(address setting). (Fig. 15)
(5) "oP-7" has now been selected for address setting.
(6) Press the ON/OFF operation button on the remote
controller. (Fig. 15) Check that the "beep"
signalreceived 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.
15)
Changing of the second remote controller address is
now completed.
