3 HVAC Systems in Ironbug in energy simulation

Hi ,

I’m just a beginer of ironbug and found a problem, that I can’t add more than 2 HVAC systems from ironbug to “HB run OSM”, which can cause a failure.

Is that the limit of software or I just make some mistakes?
Thanks for your help!

@ MingboPengIs there any idea about this problem? Thanks

Hi @YZZhang,

One model can only have one “HVACSystem”, you just need to merge all “AirLoop” and “PlantLoop” together.
