[EnergyPlus_Support] Re: Primary/secondary flow: "flow rates out of bounds"

["lee_ching_hei" <cheung5407@xxxxxxxxxxx>]

I had the same problem using pri/sec configuration. I guess there are 
some bugs with this pri/sec arrangement. Imagine if the pri pump is 
constant and sec pump is variable and both of them are connected in one 
loop in E+, how can the speed of sec pump be variable to meet the load?
I finally made 2 loops separately ( one of primary and one for 
secondary). The loops are then connected by "connection component".
I don't know if there is any better idea to solve the problems.
