RE: [EnergyPlus_Support] Re: Controller function error

Occasionally the "Controller function is inconsistent�” error is due to setpoints that are inappropriate � e.g., heating setpoint higher than cooling setppoint. E+ doesn’t handle that very well. (Neither does a real control system!)

Hello Jill,

Thank you so much for your answer. Actually I used the IDFVersionUpdater.exe to update the IDF file obtained from DesignBuilder to 8.0.0. There is no warning message. I do not know whether the error that the "Controller function is inconsistent with user specified control action = "" action" is caused by any other reasons or not. Can you give me some suggestions?

Hello Ying Yan,
A few things that may help if you haven't figured this out already.
1. If the EPLaunch version doesn't match the IDF file version, there is usually a warning saying so.
2. There is a "Version" object in your IDF file. If that doesn't match, you will usually get this warning.
3. You can try to trick the program into getting rid of this warning by just changing the version in the IDF file in a text editor, but this is merely cosmetic.
4. If you know your IDF version is 8.0 or the latest version, I would just download and install the latest version of EnergyPlus, then they should match.
Good luck,
Jill
