Subject: Re: [EnergyPlus_Support] Not sure if I can model this plant configuration
Probably I'm wrong but you could try to set a variable speed pump instead of the constant speed pump.You should place it before the splitter.So now this "variable speed pump" should work as two constant speed pumps,dont let them to set the flow(Passive).
When one boiler is switched on,it requires the nominal flow for it,the "variable speed pump" allows this flow.If your two boilers are switched on,the "variable speed pump" allows the required flow.
It works with the condenser loops in one model that I made.

Dear Forum,
The schematic I have attached is a common boiler plant piping configuration in my experience, using an individual constant speed pump for each boiler, plus a variable speed distribution pump.
Officially it’s a “primary – secondary pumping loop”.
I cannot make the prima
