HB-Legacy VRF+DOAS seems to be causing an error?

To conenct the detailed modell of VRF+DOAS with LBT model, I tried this first, haha

thanks @TrevorFedyna to lead me here IronBug Air Source Heat Pump - #10 by MingboPeng @MingboPeng 's new example gived me the right route map

Ironbug_HVAC_16_VRF_DOAS_updated with LBT.gh (81.5 KB)

Using templates method is working now, but with detailed modelling I still get this:

  1. Solution exception: ** Fatal ** GetVRFInput: Errors found in getting AirConditioner:VariableRefrigerantFlow system input. Preceding condition(s) causes termination.
