Hi all,

I am trying to design DOAS system to my existing VRF system in OS. I have successfully designed the VRF system (1 terminal 1 thermal zone). Would like to put 5.5 l/s/person precooled outdoor intake to the room, and found out that designing the air loop coupled with VRF in OS is not easy, I tried to use the measure in BCL "VRFwithDOAS". My model is simple 1 thermal zone building. And never ran successfully. Always show this message: C:\fakepath\Capture.PNG

It says the error is "Null reference for setZoneforMasterThermostatLocation", but i couldn't find any clue where to input it in the VRFwithDOAS measure, anyone can help me with this?
