Has anyone else out there had issues with Trace not accurately modeling Radiant floors?  The last two attempts at modeling radiant floors have resulted in spaces that are overheating and thus bringing on cooling in the middle of the winter (minimal internal loads, climate zone 6A - there shouldn't be any or much cooling).  My schedules don't overlap.  Most spaces are seeing there maximum temperature in January resulting in a significant amount of energy consumed in January (More than is consumed in July!).  Even setting my cooling setpoint to 85 (with a drift of 87) and my heating setpoint to 72 (with a drift of 70) results in a space temperature of 85 in the spaces.  I've discussed with Trace some and haven't gotten an answer - all I've got so far is just try this - try that - but nothing seems to work.
