Notes:
① In order to realize the MODBUS interface function, the address mode of the unit must be set
into long-distance control address mode; you can not set it into centralized control address
mode, otherwise, this function can not be realized;
② The unit can not be connected to MODBUS and centralized controller at the same time; only
one of them can be selected;
③ 255 sets of unit in maximum can be connected in the same network; the unit addresses in the
same network must be different, otherwise, the unit control will be affected;
④ Perform wiring when the unit power is cut off.
7.2.4 Connect to interface of centralized controller:
The indoor unit is with the interface of centralized controller. When centralized controller is connected,
centralized control of unit can be realized when the wired controller is not connected;
(1) Interface instruction:
1) The printing is COM-BMS2, COM-BMS3 and the interface type is B2B-XH-K3;
2) Electrical characteristic: none;
3) Working principle: centralized control the communication of indoor main board and realize the
unit control;
(2) Function instructions:
