I am trying to model single package vertical units (like this Bard product line) with economizers in eQUEST - I was thinking the eQUEST "Pkgd Terminal AC" would be a good system approximation for this equipment but then I don't believe I can include an economizer with that system type in eQUEST. Any suggestions on how to include an economizer on a PTAC in eQUEST or is there another workaround I could try?

I suggest using a PSZ in place of the PTAC. If you are concerned with part load performance, you can specify the PTAC curves for the PSZ system.

Thanks for the reply, Chris. With PSZ having to specify a return air path, would you agree Direct would be the best choice for a through-the-wall unit?
