Mismatch of equations and variables

edit

Hello all,

I am getting an error of 297 equations and 300 variables. Previous all of of my modelica buildings model have had a match. However, this time there is a mismatch, and I am not sure why. I redid the connections, but I am still getting the 297/300 error. Is there a way of debugging mismatched equation/variables in modelica other than redoing the model? Everything seems fine to me, but I am not sure why there is a mismatch. I uploaded an image of the model and its code to this post. Thank you for the help
