When using a pre-defined heat load or flow rate profile, it is possible to apply a smoothing factor over time, that averages short-term fluctuations.

In addition, the pre-defined heat load or flow rate can be scaled using the parameter `**_scale`. For the heat load this scaling factor

For a pre-defined heat load profile or a variable heat load following a cosine pattern, the flow rate in the main model

configuration (`m_flow`) is automatically scaled such that the ratio of the
