Communication of the System
When there is module combination system in outdoor units, each module in the same cooling system has to
set the module address code which cannot be reduplicative or communication error code” E6” will be
displayed. The setting sequence of module address has to be as the follows:
If the total modules in the same cooling system is 4, module sequence must be: 1 ＃， 2 ＃， 3 ＃， 4 ＃；
If the total modules in the same cooling system is 3, module sequence must be: 1
＃，
2
＃，
3
＃；
If the total modules in the same cooling system is 2, module sequence must be: 1
＃，
2
＃；
If the total modules in the same cooling system is 1, module sequence must be: 1 ＃；
Module address code is in “SW3” of mainboard.
6. Communication address setting of pinboard
When there is module combination system in outdoor units, each pinboard in the same cooling system has
to set the address code which cannot be reduplicative or communication error code” E6” will be displayed.
Address code of pinboard is SA1, and address setting range is 1#~8#.
Each module address cannot be
reduplicative and address codes in
this example are “1”,”2 ”,”3”
Each module address
code is in “SW3” of
mainboard .
