Luban - Air Purifier - Amber LED indicator

Does anyone know what the ‘amber’ colored indicator in Luban, for the Air Purifier indicates? All the other accessories show a green indicator. The purifier is working perfectly from Luban.

In addition, what is the yellow colored ‘clock’ in the screenshot indicate?

My purifier is orange when it’s disconnected from the power source and gets green when powered on.
I guess the clock is a connected “refreshing” sign.

Thanks for the response.

It never changes to green when I turn it on.
