11-1. Address Setting of the Remote Control Unit

The address can be set in order to prevent interfer-
ence between remote controllers when 2 indoor units
are installed near each other. 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) Slide the rear cover of the remote control unit, and
cut the jumper wire for address switching using a
nipper then draw away the cut wires to prevent
short circuit. Slide back the rear cover. When the
wire is cut, the address is automatically set to a
different address (Fig. 1).
(3) Press and hold the remote controller ECONOMY
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 ECONOMY
and 1HR. TIMER buttons. "P1" (Test Run)
appears, blinking in the remote controller display
area.
(4) Each time the 1HR. TIMER button is pressed, the
display changes as shown below. Press this but-
ton 2 times to change the display to "P7" (Address
Setting). (Fig. 2)

(5) "P7" has now been selected for address setting.
(6) Press the ON/OFF operation button on the remote
controller. (Fig. 2) 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 "P7" display.
