Hi. Im using Energyplus. I wanna setting humidistat in energyplus. However, im using Fan Coils HVAC system. at the first im using HVACTemplates:FanCoil. I need to keep the RH between 60-70 % and Temperatures 23-25 C.

Please anyone help me thanks.

Here my HVACTemplates:FanCoil Code

The fan coil model does not include humidity control. I suggest changing to one of the other ZoneHVAC equipment types that does allow humidity control. For example HVACTemplate:System:Unitary can control humidity.
