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

I suggest opening an issue at https://github.com/NREL/EnergyPlus/is.... I'm not seeing any other users that have hit this issue, and since EnergyPlus isn't providing any suggestions in the error message about how to resolve it, it may be an unexpected error that an EnergyPlus developer needs to look into.
