Welcome! Here are the website rules, as well as some tips for using this forum.
Have a solar install.... good sized 8 flat panels... My only install. Noticed that the solar fluid was not moving... alarmed when I saw the temp @ the panels was 320F! I started changing settings thinking that someone had messed w/ the control... looking @ the literature states that when high temps were present that no circulation takes place.
Question. Would it not make sense that when high temps were present that the best thing to do would get the fluid moving and heat transfer going on?
