This wired controller is used to control the operation of unit and conguration of the system. It can also be used
to check the system running parameter and display the status of system via the LCD screen.
The wired controller communicates with the IDU (Indoor unit) board with certain protocol, and detect
the commu- nication status at real time. IDU board will give communication fault alarm once it loses
communication. But it will not give alarm if you did not connect the wired controller to the IDU board when
power on the system. So please note that if the wired controller is not necessary, please do not connect it
before power on the system.
The wired controller will o its screen for energy saving without pressing for 35s (except the technical
parameter conguration), and will wake up once you press any button.
