[EnergyPlus_Support] Re: Error message on flow rate

["zhaicq98" <zhaicq98@xxxxxxxxx>]

I think I have corrected the error in the air loop. I have put the 
return fan as part of the outside air system. I think it should work 
in this way. However, the water flow rate error remains. I really 
have no idea what to do with regard to it.

Thanks,
Chaoqin
