Yesterday was the day that the 2nd fan kicked on for me. I noticed that it is blowing at a noticeably less power output than the bottom fan. They are both on and working its just not as powerful.
If you ever have used the standing fan in a room typically they have 1,2,and 3 speed levels. I’d say my bottom fans like a 2 maybe 3 and the top fan is like a 1. I wasn’t sure if anybody else noticed this and if this is how it is it supposed to function. Anyone?
