PCB and Functions7 - 4187654321. Outdoor Unit Control PCB1-3. Functions (for CR-CHX06052)CN51 2P plug (black): Automatic address setting pinIf the system address switch (S002: Factory setting is 0) is set to other than 0 (centralizedcontrol), press this switch once to automatically set the address of the indoor unit to theconnected outdoor unit within the same system. While the automatic address setting is inprogress, 2 LEDs (red) on the outdoor unit control PCB blinks alternately. (The automaticaddress operation will stop when this switch is pressed again.)When other system in centralized control mode is in the progress of automatic addresssetting, only the LED1 of the outdoor unit control PCB blinks and indicates that theautomatic address setting for other system is in progress. While other unit is in the progressof automatic address setting, pressing S001 will disable the automatic address setting.••S002 Rotary switch (10 positions, black): Outdoor system address setting switchThe factory setting is 0 (1 system control), but it is necessary to set the address to eachsystem with the multiple system control or centralized control. (Fig.7-1)When system address is set to 0, automatic address will start simultaneously with poweractivation, and it is not necessary to set the automatic address setting with SW01 switchwhen there is only a single or simultaneously running multiple controls in a single system.When multiple systems are operated in centralized control, maximum of 30 systems (upto indoor unit 64 units) can be connected. When operated by group control or centralizedcontrol, set the system address other than 0 (1 or more).When the number of systems exceeds 9, you can set up to 30 systems by combining withthe dip switch S003. You can set up to 39, however control will be for 30 systems even if youset more than 30. (For details, refer to Table 7-1.)LED1 of the outdoor unit control PCB lights up and the warning “ ” is displayed in remotecontrol when the system addresses has overlapped (multiple equated addresses exist).•••••S003 DIP switch (2P, blue): Switches for setting system address 10s digit and 20s digitIf 10 systems or more are set, the setting is made by a combination of this DIP switch andS002.If 10 - 19 systems are set, set switch 1P (10s digit) to ON.If 20 - 29 systems are set, set switch 2P (20s digit) to ON, and set switch 1P (10s digit) toOFF.If 30 systems are set, set both switch 1P (10s digit) and switch 2P (20s digit) to ON. (Fordetails, refer to Table 7-1.)••••CN14 2P plug (white): PCB inspection pin at the factory
