*: The matrix is composed of 4×16 grids and each grid is composed of two blocks of different sizes. 
The matrix include horizontal coordinates 00-15 and vertical coordinates 00+, 16+, 32+ and 48+, 
which indicate the  address of  the  indoor unit.  The  sum of  the  horizontal coordinate and  vertical 
coordinate of the grid is the address of the grid. Each grid corresponds to an indoor unit of this 
address. 
 
3.4 Operation instructions 
1) System composition:   
  The  centralized  controller is  used  to  perform centralized control  and  data  query for  the 
network air conditioner. Each centralized controller can communicate with a maximum of 64 
air conditioners to make up an air conditioner LAN, and implement centralized monitoring 
for the air conditioners in the network. 
  The  centralized  controller  can  be  interfaced  with  computer  or  gateway  to  implement 
centralized  control  and  status  query  for  all  air  conditioners  in  the  network.  It  can  be 
connected with WAN via computer or gateway to implement remote computerized control 
(with support of computer software). Each local computer or gateway can be connected to 
16 centralized controllers as a maximum. 
  The  master  or  slave  answer  mode  is  implemented  for  communication  between  the 
centralized controller  and the  air conditioner, between the computer and the centralized 
controller. In the LAN composed of centralized controller and air conditioner, the centralized
