RESOLVED - Hot2000 CoefA Error

    I am wondering if anyone else has experienced this error message and knows what is causing it:

    "Zero CoefA 0.0000"

    Yes, I had this the other day.  Didn't quite figure it out yet.  I think it may be about a "0" entry being somewhere.

    I'm pretty sure that is a problem with your blower door test results. Try using calculated instead of actual ELA?

    Fixed the error in my file.  It had a generic DWHR but no model selected.  So there was a 0% Efficiency.

    Resolved for the time being.  Our internal QA found that deleting the Efficiency upgrades resolved the issue.  I had an Integrated HP DHW selected, so it may have been the efficiency selected for that.  I will test again later.  At least for now I can proceed with my E file.

    Thanks for feeback all.
