Good morning, all,

I'm encountering a run-time error trying to model duct heat loss. Normally when eQUEST has a run-time error I can find the cause of the error by searching for "error" in the .BDL file, but not in this case. I am entering 2F for DUCT-DT to simulate the temperature rise of the supply air through the duct. I also tried raising the Zone Entering Min Supply Temp, but the error still occurred. Any suggestions?

The attached files are from version 3-65.

Thanks,
