The original Programme will do a 5 minute scan of your grow room and calculate the gradual increases and decreases of your fans, in the course of the scan it will automatically find the capacity at which level to run your fans to maintain a controlled temperature - this means less work getting temps just right, as the unit will do it for you!

The second programme activates when the grow rooms lights have been switched off to simulate the dark period - when the lights are shut off, the Twin Controller PRO 4.5A kicks into action, it calculates the humidity within your room and any excess is abolished due to the Twin Controller PRO 4.5A gently increasing the fan speeds for just the right amount of time to remove the excess humidity from the grow room.
