Hello,

I've created an EnergyPlus model for my apartment and want to conduct some analysis on that. I get results when I set the setpoint to 23C, but when I change the setpoint to 25C, it gives me this error:

* Fatal * Unable to determine fan air flow rate.

I have used HVACTempleta:Zone: PTHP in my model. Does anyone know why I get this error?

You can find both files in this link.

Thanks for your help in advance!

Thanks, Mostafa
