I installed this on my roof a couple of years ago.
Removed because I had a new roof installed with excess standard vents and just don't need it.
Comes with the temperature controller so the fan starts at preset temperatures.
Works as it should.
It is an electric setup so needs AC power to run.
New this cost over $100
I will take $20 just to not have to store it.
No E-mails. I don't check it often enough
