Re: [EnergyPlus_Support] Solar collectors: "Branches cannot handle all the flow"

hello,

i had the same problem in my hydronic low radiant system, and i solve it by putting 0 in maximum flow rate for each branch, because this field is required for air loops and not for water loops.

I'm trying to model solar collectors (again!). I want to model solar collectors as follows:
oooooooooo
oooooooooo (o = solar collector)
oooooooooo
oooooo

When I model collectors as follows:
oooooooooo
o
o
o

An error occured :
** Severe ** Branches cannot handle all the flow. Possible causes could be absence of Bypass,
** ~~~ ** or components that are manually sized incorrectly. Consider autosize where possible.
** ~~~ ** To fix add a Bypass branch or size the other ACTIVE/PASSIVE branches to equal the loop flow
** ~~~ ** Occurs in Plant Loop=DHW LOOP
** ~~~ ** Occurs for Splitter=DEMAND SPLITTER

But, all my components are autosize!! Thus, my installation doesn't have any bypass, so I don't want to model bypass!
Is there anybody able to solve this problem?
