This window unit can go as low as 64 degrees Fahrenheit can control it with the remote, phone, or the unit itself. The back light automatically turns off on the unit. There are three settings for the mode cool, fan only and energy saver. There are also four settings for fan low, medium, high and auto. I always keep it on auto.  Keeps my entire 1 bedroom apartment cool. I enjoy coming home because I can walk through the front door and get hit with cool crisp air. I don’t have centenal heat or ac I have radiant heat in my apartment. The only issue I have with it is that it is sort of loud but I’m fine with it as it is in the window directly behind my bed and all ac units are loud.
