How can I fix the humidity in the zone, using HvacTemplate objects?

Hi, all. I'm modeling a building with enrgyplus 8.1.0.009 and using the HvacTemplate objects with following combination:

HvacTemplate:Thermostat;
HvacTemplate:Zone:ConstantVolume;
HvacTemplate:System:ConstantVolume [all setting for humidity (humidification & dehumidifcation) done here];
HvacTemplate:Plant:ChilledWaterLoop;
HvacTemplate:Plant:HotWaterLoop;
HvacTemplate:Plant:Chiller;
HvacTemplate:Plant:Boiler;

Unfortunately, I've no control on humidity as the spreadsheets shows. should I add other objects like Humidistat, Humidifier, Dehumidifier, etc. or the data set in HvacTemplate:System:ConstantVolume are incorrect? I'd be grateful if somebody could help me.

Short answer you will need humidistat and some means to dehumidify you space (dehumidifier or HVAC) and humidifier if your weather calls for that. You can start by reading that post and also that one. Though both are answers for OpenStudio you can get the general idea of how to do that.

You can look at 'DesiccantDehumidifierWithAirToAirCoil.idf' example file which you can find under the exampleFiles directory in your E+ installation directory.

Generally speaking you might want to use the 'ExampleFiles-ObjectsLink.html' to find examples with Objects of interest. Also you can use the ExampleFiles.html to find what is inside the example files. Both html files are also located under the above mentioned directory.

Thanks a lot dear Sir. but please be informed that I've modeled it by Ecotect 2010. I wonder if it impacts on your answer. Also I thought that it is not needed to extra objects like dehumidifier while using Template combination because humidity setting tabs inserted in HvacTemplate:System:ConstantVolume. By the way, I'm seeking Coil-Reheat type of dehumidifier and I don't like Desiccant type because I think it's mechanism differs from common type (I mean: Coil-Reheat). Anyway thank you for those information and I'd be grateful if you answer again my problems.
