2.1.3 Function description of each part
System composition:
1.
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.
2.
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.
3.
The master/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 controller is a master, and the air conditioner is a
slave. In the LAN composed of computer and centralized controller, the computer or gateway is a master,
and the centralized controller is a slave.
