I am using Openstudio/Sketchup version 3.2.1. I want to create 1 system Chiller with many FCU and no AHU, I have 2 questions.

Question 1: I read in the article that I don't have to create an FCU in the air loop on the HVAC tab, just have and that these are added as zone equipment on the thermal zones tab. If so, what is the plant loop ring for?

Question 2: I want to control the load chiller according to my wishes, but in Openstudio I do not see, how should I do it. May everyone help you Link article: https://unmethours.com/question/53061...
