modelTerminalUnitScaling

Validation of the scaling factor of the terminal unit model

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This example validates the use of the unit multiplier and zone multiplier factors for models of terminal units inheriting from Buildings.DHC.Loads.BaseClasses.PartialTerminalUnit.
