[Equest-users] Add-On Desiccant for simulating passive dehumidification wheel?

Any thoughts on using a System -> Preconditioner -> Add-On Desiccant for modeling a passive dehumidification wheel in the configuration shown below?
It would be a workaround. One problem I see is the Add-On Desiccant doesn't interact with the return air. You would have to derate the total energy wheel somehow, such as by reducing the effectiveness or decreasing the exhaust airflow.
