This controller will adjust the speed of your fans and has 5 step transformer that ensures there is no electrical noise, buzzing or humming when you fans are running at a lower speed unlike other controllers. This in turn makes it work very well with acoustic and large fans. It will keep you room within +/- 1 degree of your set temperature.

We recommend that you're outtake fan is about 25% more powerful than you intake fan to create negative pressure in your growing environment.
