[Equest-users] Curve Fit

[James Chong]

When you open equest, you should be able to 'continue and remain in program' or 'exit'. If you continue, you should be able to change your boiler link and performance curve.

If not,

Try this. Make a backup of your INP file. Open the INP file using notepad or some sort of text reader and search for "boilers". You should be under the Boilers section between Chillers and Domestic Water Heaters. Delete the lines with HIR-FPLR and HIR-FT (if they exist). This will restore default to your performance curves for your boiler. Save and close and try it now.

If that doesn't work, search "performance curves" and delete the entire curve that you think is giving you problems. Also make sure you delete anything that is referencing that specific curve or you'll run into other problems. Do this by searching the performance curve name and removing the lines of code that references it. Note that all this is doing is removing your custom curve and setting everything to default. You will have to re-create your curve again.

Unfortunately, I'm not given enough information on why the error is being caused. Some possibilities are that the boiler referencing a curve could be misspelt; object names should be no longer than 32 characters or they get truncated resulting in the first possible error; "&D" is a predefined default code for mandatory numeric values (not for string values, I think).


I hope this helps.

Hello,

I somehow created this error message and don't know how to get rid of it, can anyone help?

Curve Fit
    unknown/invalid component name
        &D was referenced on line 5228 but never defined

There is no error managing window, and this error appeared after I modified the Heat Input ratio performance curve for a Boiler.

Thank you,
