[TRNSYS-users] Temperature difference

[David BRADLEY]

Michele,

   it is a bit hard to see the picture but it looks to me as though the 
TGROUND input is unconnected and set to an initial value of 0. That 
means that your building thinks that the ground temperature is 
constantly 0C.

kind regards,

  David
