I'm creating a model of a direct evaporative cooler. Is it possible to set the relative humidity of the evaporative cooler's output node to a fixed percentage, say 80%?

I figured out how to address the issue using EMS on EnergyPlus. Thanks so much.

I customized my evaporative cooler setting by going through the EMS code on the "EMSAirflowNetworkOpeningControlByHumidity.idf" example file. The control of my evaporative cooler was achieved using an input node sensor and an output node actuator, as well as a 'near-linear relationship' between the dew point and relative humidity.
