Ordered two of these described as exhaust, but I received the 2 intake models. If the display is facing you and it kicks on, the air blows in your face. That is the opposite of what is shown in the pics and description. Otherwise the fan works fine. I only wish you could disable the beeping when the alarm temp or humidity kicks on. Also it would be nice to be able to remove the display and mount it somewhere else like other ac infinity fans. If I ever want to see or change the setting, I have to crawl under my house.
Runs on almost no energy. Electrical current downsized by converter to power fans. Motors have long life expectancy. Keeps heat and moisture out of crawl spaces, Attic and basement. Big energy saver as intense heat is taken out of attic and exhausted to outside.
