Primair fan controller question

[ZAGNZAD]

Hi all this is my first post.
Got a question about the primair fan controler?(pic 1)
If you set the temp at 78 were would you have the inlet and outlet control set at? This is in a attic room 14ft by 12 ft running with 1x 315mm rvk inline fan on the inlet and 1x 315mm exaust fan with phat filter.Any input would be greatly received,thanksZ.Z

Never used one i'm afraid but I gather the idea is to set the temperature that you want the fans to go on full speed in this case 78F. The other controllers are used to set the individual fans speeds, that is the speed they are running at when not needed for flat out cooling. This is to provide air movement through the room. I would try 50% for both at first and see how that affected the temp and humidity then adjust from there. If you're bringing in outside air in the colder months 25% would probably be a better starting point.
