Indoor Pool using EnergyPlus

I'm working to setup a standard indoor pool system in EP following the 5ZoneSwimmingPool example file. The pool object (SwimmingPool:Indoor) appears to running correctly in my test model (based on output variables), but the water heating system never activates despite the pool water temperature sitting well below the setpoint. The IDF was created using OpenStudio, but I have an EP measure adding in the pool object as well as the entirety of the pool heating system so I may have missed something in this translation. The model runs fine (in OS and EP-Launch) but I'm unable to find the issue with the heating system. Any thoughts?

Looks like its related to this: https://github.com/NREL/EnergyPlus/is...

Autosizing doesn't seem to work with this system, but hardcoding the boiler flow and loop max flows seems to have fixed the problem. Thanks.
