Don’t Understand VPD or what to do about it?

Ok here ya go. Its the basic setup for running automations. My system just updated again so i imagine i have some settings to play with whenever i get them.

The only thing to do other than whats on this is set your times on and off. The system will adjust everything else. Also dont bother setting up your fans for automation. I just run mine around setting 4, 24/7.
