modelling water to water heat pumps from ground loop to radiant heating and cooling

Any suggestions on how to set up radiant heating and cooling sourced
from a ground loop?

I am nervous about using water to air units and zeroing out the fan
energy but that's where we are starting. Will the loads calculate
properly where heating setpoints are in the low 60's?

Any help at all would be super.

Thanks in advance!

One thing you can do is to manually adjust the FLOOR-WEIGHT for each
space, especially if this is radiant slab, to "give a longer lag time
between heat gains and resultant cooling loads, and greater damping of
peak loads". [From the help menu text.]
