extends Buildings.Templates.Data.AllSystems;
/*
The construct below where a replaceable model is used inside the `outer`
component declaration is for validation purposes only, where various configuration
classes are tested with the same instance name `VAV_1`.
It is needed here because
- the `inner` instance must be a subtype of the `outer` component, and
- the `outer` component references only the subcomponents from its own type
(as opposed to all the subcomponents from the `inner` type), and
- modification of an outer declaration is prohibited.
The standard export workflow should use an explicit reference to the configuration
class for each MZVAV model instance.
