Through the deployment of class-wide air-conditioning installation, class-wide air-conditioning installation provides the work class with a quick and correct installation process. The work class can clearly understand the equipment that the assigned school needs to install through the information displayed on the app, such as: air-conditioning controllers, Gateway, school-wide summary list, etc. By scanning the QR Code on the device and taking a photo to create a file and pair the device online, you can monitor the air conditioner remotely.
