dude- calm down.

1. Read the rules- no DIY instructions on this site. If you are not comfortable with what you are doing- go to vegas and waste your money there- becasue you are about to risk frying a 5000 dollar HVAC system to save a few bucks.
2. There are many different models of Vision Pro to fit particular systems.
