[TRNSYS-users] ready example of ground-source heat pump

[David BRADLEY]

Kent,
   I think those examples are too basic for what you are trying to do 
although they might serve as a starting point. They basically have no 
controls in them at all. You would also need to use Type682 or Type693 
from the TESS Loads and Structures library in order to impose your 
precalculated loads on the heat pumps.
Kind regards,
  David
