          the pigtails wire need to be at least a few inches longer. my installer could not reach a roof joist to mount the control box. So i called/complained to the customer service rep. As for how long it works / function of control box and fan motor, only time will tell. Also when purchased the fan, the box could say i am not getting the controller. that's a bit misleading.

          Works okay, but overpriced
          These seem to do the job, but the quality of the manufacturing is pretty low. The temp and humidity adjusters barely even line up with the holes in the housing. Additionally, they were just in the box with some paper with no literature at all. You just have to guess whether the temperature and humidity settings work together or independently and how to set them.
