[TRNSYS-users] TSGRD in starnode mode

[Antoine Gautier]

Best wishes to all Trnsys users

I'm starting the year with a little question about the use of Type 56 input variable TSGRD under the starnode (standard) radiation mode.
Is this temperature used (with Tsky) in the calculation of Tstar for longwave radiation exchange with external surfaces? 
Or is its use strictly restricted to detailed radiation mode? In this case, what ground temperature is used for the calculation of Tstar for longwave radiation exchange with external surfaces? 

Thanks a lot for your help.
Best regards
