Caution: The address can be not beyond 0~3; The address of each outdoor unit must be different.
Address code setting for outdoor unit Address setting switch for communication of network (CCM02) Because the CCM02 can be connected with 8 groups of outdoor units, each outdoor unit need two switches to label the address
For the address of different group
For the address of different outdoor unit in one group
Caution: Only when outdoor units are connected with CCM02, the above two switch need to be changed.
