64 Outdoor Unit
Main unit and Sub unit PCB
DIP switch setting
■ Checking according to dip switch setting
1. You can check the setting values of the main outdoor unit from the 7 segment LED and those of the
sub outdoor unit from the LED. The dip switch setting should be changed when the power is OFF.
2. It checks whether the input is properly performed without the bad contact of the dip switch or not
■ Checking the setting of the main unit
The number is sequentially appeared at the 7 segment in 10 seconds after applying the power.
This number represents the setting condition.
For example, R410a 30HP(Combined 10+10+10HP), Normal mode ;
Main model code ➨ Sub1 model code ➨ Sub2 model code ➨ total capacity ➨ 3 ➨ 25 ➨ 41
(93) (97) (97) (30)
1~255: Main model code
1~255: Sub1 model code
1~255: Sub2 model code
5~40: HP number(sum of main capacity and sub capacity)
1: Save mode 3: Normal mode 4: Capacity up mode
25: Normal
22: R22 model 41: R410a model
■ Checking the setting of the sub unit
It is displayed by 8 LED of the sub unit. A set of two LED's represents 0, 1, 2 and 3 in binary.
LED1, LED3, LED5, and LED7 are least significant bit of each digit.
LED2, LED4, LED6, and LED8 are most significant bit of each digit.
1) LED2, LED1
00 : 8HP unit 01 : 10HP unit 10 : 12HP unit 11 : 14HP unit
2) LED6, LED5
00 : - 01 : sub1 10 : sub2 11 : sub3
3) LED8, LED7
00 : normal 11 : data display
CAUTION
Product may not properly operate if the relevant DIP switch is not properly setup.
