Re: [EnergyPlus_Support] Warnings



Mike my coil is DX:coil: Multispeed and it is outosized, where i could find out the min actuated flow rate that you mentioned. Any how the file is uploaded under name VAVEnvolpBuild_fivZone could you please have a look to it.
 
Thanks in advance

In some systems, the cooling coil model may generate such errors during initial 
iterations at very low load conditions. Which cooling coil model are you 
using? What is the min actuated flow rate in the controller for this coil? If 
it is zero, try setting it to a small value, such as 0.00001. If this does not 
help, please post the input file.
