I did that once using CAV DX unit.

I cant exactly remember because I don't have HAP in front of me but it
should go something like this:

1. you set up your room as usual. allow for some small quantity of
outdoor air in l/s
2. Set up DX CAV airhandler and choose supply air by quantity not
temperature. Use same amount of supply air as outdoor air in step 1
3. use direct exhaust from zone and set it up at same amount of air as
in step 1 and 2
4. use indoor temperature that you are targeting.
5. run hap and look at the coil load. If coil load is positive figure
increase air quantities in step 1, 2 and 3
6. run hap again and keep increasing air quantity until you get 0 for
coil load 

And that should be it than.


Regards
