I faced the same issue and did some experimenting. Hopefully it will save someone else some time.
Here's what I tried: Add the HX before the splitters on the CHW and CW loops. Instead of selecting the actual chiller inlet and outlet, select the CHW splitter inlet and CW splitter inlet. The thought being that E+ might stop the flow at these nodes when the HX is off. The simulation crashes because of the incorrect node selection. I confirmed that this is the cause by successfully running the simulation using "CoolingDifferentialOnOff" as the control type.
