Re: [EnergyPlus_Support] warning

The performance curves essentially describe how your coil works. They ARE your coil. Your coil (i.e. your curves) was not intended to work with such low incoming temperature air.

Hi, 

I  receive below warning when I try to run my IDF file. I used " HVAC Template Zone: PTAC" for the model.  I changed everything I thought it may related to this problem; however the warning did not solved. But When I try to run the IDF file with another city weather file or  with added shading device to the model ,this warning  will be disappeared.  

Would please give me some advice about this issue. How can I solve it.

Thanks in advance
