Hello, I am wondering if there is any way how to solve the cascade of several boilers feeding for example heating collector. Is it possible to make a multiple hotWaterRef for one equip? In this case collector, e.g.:

id: @heating.collector equip hotWaterRef1: @boilerA hotWaterRef2: @boilerB . .

I suppose that not, but is there any solution for this?

And also I am not sure how to tag heating collector. There is no any special def for it in the list of equipments, may be using "plant" can be correct?

Thank you for you ideas

Yes, all your flow refs may be a list of refs if its one-to-many

id: @heating.collector equip hotWaterRef: [@boilerA, @boilerB]

Also see how filters work for that use case

Perfect, thank you very much
