Hello, I am using fan coil systems with boilers and chillers for simulating and I want to add humidity control to the building model, could you please guide me what all class lists do i need to assign to get humidifiy control to the model?

I have used Zonecontrol:Humidistat and Schedule:constant for now but after simulating with this class lists assigned to the model, it does not have any change than previous. it shows same load before and after applying this class lists.

I am missing something here, could you please let me know is this the correct way oy assigning or I need to assign extra class lists to make this run.

Thanks in advance...

In addition to the zone humidistat, you also need to add components to the air system serving the zone that add or remove moisture from the supply air. Dehumidification can be achieved by UnitarySystem's Dehumidification Control Type field, ZoneHVAC:Dehumidifier:DX, Dehumidifier:Desiccant:NoFans, or Dehumidifier:Desiccant:System. Humidification can be achieved with Humidifier:Steam:Electric or Humidifier:Steam:Gas.
