7-6. 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.
Jumper wire for address switching
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. 13).
(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. 14)

(7)Finally press the remote controller ACL (Reset) button to cancel the blinking "P7" display.
