Overview

This issue is caused by removing all of the HVAC systems from a project using the HVAC Manager. Once this is done, you will not be able to access the HVAC Manager again.

Method

• Create a new project
  
  
• Using Windows Explorer, go to the new project folder and then into the Hvac folder. there should be 3 files in here:
  
  UserHvac - Steadystate heat gain and loss.XML
  UserHvacHeader.xml
  UserHvacindex.xml
  
  
• Copy these files into the corresponding HVAC folder in your existing project folder.
  
  
• You should now be able to open the existing project and access the HVAC manager.
