I am trying to run the attached E+ file which I transited from 8.8 to 8.9. But It is giving me some errors which I am not able to solve it. So, I would appreciate it if anyone can take a look at it and provide me with some suggestions. I also attached the schedule files that I am using in this E+ file.

Also, I attached the Err file that I am getting. Thanks.

@MJWitte Please find attached the V8.8 version of the file in the following directory:

I can reproduce the problem. New issue #6875 posted. Some files transition correctly with the new variable name, but this one does not.

This is the part of your error file that is referencing the key culprit:

** Severe  ** Invalid Output:Variable or Output:Meter Name =HEATING COIL AIR HEATING ENERGY
**   ~~~   ** Entered in EnergyManagementSystem:Sensor=DELIVEREDHEATING_1
**   ~~~   ** Output:Variable Name not found

Basically, EnergyPlus is saying that HEATING COIL AIR HEATING ENERGY is not a valid Output:Variable object key name. The referenced DELIVEREDHEATING_1 is the name of a Coil:Heating:Fuel object in the model. From the I/O ref for this coil object, the output variable you want is Heating Coil Heating Energy (no "Air"). This may have been a renaming of output variables for this coil object to include "Air" for v8.8, then remove "Air" for v8.9, and the transition version tool didn't catch it correctly.

To fix this, you should alter your EnergyManagementSystem:Sensor object like so:

  DeliveredHeating_1,      !- Name
  Furnace Heating Coil_1,  !- Output:Variable or Output:Meter Index Key Name
  Heating Coil Heating Energy;  !- Output:Variable or Output:Meter Name

@M 108014 you're welcome. Is this really a duplicate question? I don't see another post of yours similar to this one.

@Aaron Boranian I thought that we just need to close the questions after we found the answers because I saw earlier that one of the persons who answered my question closed the question. So, I just closed it. I am sorry, I did not mean to ignore your significant help. Sorry again.

@M 108014 ah I see. I closed your other question because it was very similar to posts people had made about output variables. If you're satisfied with this answer, click on the check on the left to let others know that it solved your problem.

@Aaron Boranian Done. Thanks again.

check a templete EnergyPlus 8.9 .idf file in the examples directory and open it how .txt file, verify the sintaxis and structure of the file 8.8 file and make it like 8.9 file, then save it and run
