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 protocols and detect the communication
status in real time. The IDU board will activate the communication fault alarm once it loses communication. However, it will
not send the alarm if you do not connect the wired controller to the IDU board with the system power on. Hence, if the wired
controller is not necessary, please do not connect it before the system is powered on.
The wired controller will shut down its screen for saving energy without needing to press for 35s (except the technical
parameterconguration),andwillwakeupifyoupressanybutton.
Application of the wired controller:
j Power supply: Take power supply from IDU board (12V power supply);
kWorking temperature range: -300C~500C
lWorking humidity range: RH10%~95%
Wired controller can be installed inside your home or on the unit itself for split types. This manual provides guidelines on
