Minimum Heat Pump PLR in HVACTemplate:System:VRF is not changed

I am a bit surprised but yes the min PLR for the VRF HP is hard wired at 0.25. That should be fixed.

 CALL CreateNewObj('AirConditioner:VariableRefrigerantFlow')
 CALL AddToObjStr('Minimum Heat Pump Part-Load Ratio','0.25')

Work around: place idf file in same folder as ExpandObjects.exe as in.idf. Double click ExpandObjects.exe. Rename expanded.idf to new file name. Edit new file and change VRF heat pump minimum part load ratio to desired value.

Fixed for v23.1 in PR 9708.
