A parameter record always needs default values

Describe the bug AixLib.Utilities.Sources.HeaterCooler.PartialHeaterCoolerPI does not have a default parameter selected. For instance see model AixLib.ThermalZones.HighOrder.Validation.ASHRAE140.Case620. The parameter zoneParam is empty (by default). Normally this should be no problem since no parameter of this record is used. According to this section in the Modelica Specs a model needs to be locally balanced, which is the reason for this issue.

To Reproduce Steps to reproduce the behavior:

  1. Go to AixLib.ThermalZones.HighOrder.Validation.ASHRAE140.Case620
  2. Simulate
  3. See error message

Expected behavior Although, recOrSep is on "Separate", a default parameter for zoneParam must be selected.

Additional context Although this is a bug report, I woul recommend to merge later into development

Approach to solve issue

  1. Create a dummy record with non-physical parameters that is then the by default selected record zoneParam in AixLib.Utilities.Sources.HeaterCooler.PartialHeaterCoolerPI.
