I'm trying to add a Water Cooled Chiller to a prototypical building. I downloaded the "AedgOfficeHvacVavChW" measure from BCL and tweaked it a little bit to be used for different HVAC systems depending on user input. In case the user input is "Water Cooled Chiller", the setcondenserType command doesn't work for "WaterCooled" and whenever you try to set it to "WaterCooled", it defaults back to "AirCooled". Has anyone else faced the same issue or knows whats going on here? It works perfectly fine when you're changing the condenser to "EvaporativelyCooled".

My cursory look at the OpenStudio source code suggests that the chiller needs to be connected to a secondary PlantLoop before setting the condenser type to WaterCooled.

Thanks for the comment. So, I have to make the condenser (secondary) loop first and then set the condenser type to WaterCooled?

Here's an example of it being used.
