Instruction: 
(1)  Indicator of main board (digital display tube) “LED1” and four button: “SW1”, “SW2”, “SW3” and 
“SW4”: 
(2)  “JUMP1”: jumper cap of   the unit. Jumper cap No. varies from different type of unit. 
(3)  DIP switch “SA1”, DIP switch varies from different cooling capcity, before leaving the factory, 
DIP switch is set for different models and fixed with glue. 
(4)  The main control function DIP switch “SA6” is used to set master module and subsidiary 
module, the defaulted factory setting is the main module. As the fig is shown, dialing to “ON” 
side represents “0” and dialing to the figure side represents “1”, the defaulted setting for the unit 
is “00”. For the system with two outdoor units, one of them shall be set as the main module, 
namely, dial “SA6” to “00”, then set the other unit as subsidiary module, namely, dial the “SA6” 
to “10”.
