Outside air load

I've set up my building and tried to run CIBSE loads to determine max and min loads. The results I'm getting are about half of what I'm expecting. Digging into it further it appears the outside air hasn't been calculated adequately, particularly the latent component.

I've set up the outside air supply in the Building Template Manager as an Air Exchange, Auxiliary Ventilation, and the airflow comes out correct in the results.

There is a Plant (auxiliary energy) drop down box on the room conditions tab of the BTM, which I've set to heating profile. I can't find out what this controls from the help files.

Can anyone assist?
