Default Unrealistic Temperature in chtMultiRegion Case?

Hey guys!

My Case:

- chtMultiRegion, 2 solids, 1 fluid (air)
- first steadyState simulation with T_fluid=T_solid and turbulence on

- then i take the solutions (except T) for the fluid region and put them in in the 0-folder
- transient with higher Temperatures for the solid regions

- Version OF7

my Problem: the Temperature of the fluid is 288.15 K. in both steady state and transient simulation the temperature falls below 288 K (around 286 K), which makes no sense, since 288.15 is the lowest temperature possible in the whole domain.

How is that possible? Is it a problem with the mesh or the boundary conditions?

I attached some of the Case-Files for the fluid region. Unfortunately I can not share a lot more information.
