I have several sites already running using spyders on vvt systems, I am wondering how some others have done theirs. Example would be appreciated but the basic logic would do. I have posted on hw's building forum but that is like talking to the wall.
Are you using venoms? If so which one and what links are you using? How are you determining when and how long to go into heat or cooling? Are you switching back and forth when you have demand for both heat and cooling? How are you determining the demand? Most importantly, are you and the customer satisfied with the results?
