I'm about to model a zone which employs a simple DX dehumidifier, something that looks like an EnergyPlus ZoneHVAC:Dehumidifier:DX.

I have not used that object before. Trying to understand what it's features and capabilities are sent me to the I/O Reference and Engineering Reference.

These do NOT seem to explain how the zone humidity is controlled by this device. Can I assume that a zone dehumidification setpoint will take care of control?
