How do I model dedicated exhaust fan for enthalpy wheel for eQuest?

I am using eQuest. I am modeling an enthalpy wheel. I have input the parameters of the wheel, the coils and supply fan for this air handling unit. I cannot find where the exhaust fan is supposed to be entered into the system that uses the Supply/Return fans as the ERV fans. I have added in a relief fan and set the airflow equal to the exhaust airflow through the wheel but when I run that simulation I get minimal performance through the wheel. I am assuming that is because the relief fan is relieving the space and not pulling the air back through the wheel and exchanging heat with the outside airstream.

What is everyone else doing to model enthalpy wheels that have a supply fan and an exhaust fan? I look forward to hearing how everyone else has been modeling their units. Thanks so much in advance!

From memory (no eQuest on Unix...) you can put a supply and return fan for your entire system. The ERV wheel itself should have a "fan kW" keyword too that may be of help.
