7-1. Address Setting of the Remote Control Unit

The address can be set in order to prevent interference between remote controllers when two Sanyo 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. 13). When the tab is removed, the address 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"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.
