[EnergyPlus_Support] Re: VolumeFlowperRatedTotCap out of range

Hi

This error has been fixed. I did overlooked the branch air volume.

Now I put a HP per zone ,and found that the indoor temperature set 
point can not be met in summer.  It can be satisfied by manually 
enlarging the cooling capacity of DX coils. Could anyone give me 
directions what is happening about the autosizing?

Also, similar situation happens to the supplemental heating coils.
I have reuploaded the file onto the website.

Kind regards
Eric
