1. Presentation 1. Presentation
This wired controller is used to control the operation of the unit and configuration 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 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 configuration), 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); k Working temperature range: -300~500 l Working 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 how to use this interface effectively. If you have any questions regarding the display and its configuration, please contact your installer for more information. Caution: · Do not press the button of wired controller for 5s after power on. If you have any questions regarding the display and its configuration, please contact your installer for more information.
