I am trying to intergrate the ScrollWaterToWater heatpump component in my model from the Buildings v8.0.1. lib.(Buildings=>Fluid=>Heatpumps=>ScrollWaterToWater)

To get an understanding of its usage I first tried duplicating the ScrollWaterToWater_OneRoomRadiator example, where this component is being used. Though when duplicating this model into my own package it seems to copy everything except the ScrollWatertoWater heatpump, thus I added that later identical to the example.

  ScrollWaterToWater heaPum(
    redeclare package Medium1 = MediumW,
    redeclare package Medium2 = MediumW,
    redeclare package ref = Buildings.Media.Refrigerants.R410A,
    dp1_nominal=2000,
    dp2_nominal=2000,
    tau1=15,
    tau2=15,
    show_T=true,
    energyDynamics=Modelica.Fluid.Types.Dynamics.FixedInitial,
    m1_flow_nominal=mHeaPum_flow_nominal,
    m2_flow_nominal=mHeaPum_flow_nominal,
    datHeaPum=Data.ScrollWaterToWater.Heating.Daikin_WRA072_24kW_4_30COP_R410A(),
    T1_start=TRadSup_nominal)
    "Heat pump"

This give me the following error:
Function Data.ScrollWaterToWater.Heating.Daikin_WRA072_24kW_4_30COP_R410A not found in scope model.


I thought this might be the case because the package is located in the buildings lib and not in my own package. Therefore I added the files to my package and reverenced them again in this new location. Though I now get the error that I have more variables than equations.

How should I properly add the data to the Heatpump? And why do I get the first error?
