When losses are defined for a heating hot water loop (baseboard radiators)
in my model, the results are that the model uses more energy with a higher
loop loss, and less energy with a lower loop loss. It seems as if there is
a sign error (positive/negative) on the value entered for the loop loss
(when it is a heating loop).

The PS-D report shows a positive heat gain from "losses" to the heating
loop, as if it is a cooling loop.

Has anyone else had this problem, or has gotten the heating loop loss
parameter to give reasonable results?
