I had this installed last August. I don’t have wifi and wanted to use the scheduler, but there is no manual way to use it :-(  After it was installed, the next morning I had bright sunlight shining through the air conditioner into my eyes.  I had never heard of sunlight coming through an air conditioner, but apparently it’s a new thing now that they use styrofoam inside :-(  I am still trying to figure out what I could possibly do to block the intense sunlight??  This is a huge problem for me as I try to keep my room dark.  It is noisy, especially on the hi setting and actually was shaking my window.  I thought it would do more cooling than it does, I wanted it for 700sq. feet and was told that this would do it and has the correct amount of BTUs, however now I see that it is only rated for 550 sq, feet.
