2.1 Indoor centralized controller
2.1.1 The functions of indoor centralized controller include transmission of status information of
indoor unit to the computer and of the control and query commands from the computer, and
meanwhile it can query for the status of indoor unit and send control commands.
2.1.2 Overview of indoor centralized controller

An indoor centralized controller and 64 YDS indoor units of air conditioner form an air
conditioner LAN and thus centrally control all the air conditioners within the LAN, where various
control commands can be sent to the indoor units and status can be set up to satisfy various
control requirements. The control signal of centralized controller can be sent up to 1200m.
