PTACs don't typically specifically have humidity controls, but if you lower the supply air coming off the PTAC it may reduce the humidity issue. You can also, in Detailed Mode, play around with the "Design inlet /outlet air humidity ratios" on Cooling Coil, which may increase the latent capacity sizing.
Regarding the mechanical ventilation portion, you can check the "Outdoor air supply" box on the "Edit PTAC Unit" dialog in Detailed HVAC. Then you should be able to specify a flow.
Speaking of Detailed HVAC, it seems like this issue warrants switching into it from Simple HVAC. I seldom use the Simple HVAC module other than for purely massing/daylight-type studies.
