    Just had a Navien 240A installed with a thermal bypass valve for recirculation. The dip switches are set to:
    1 - ON
    2 - ON
    which are the settings for Intelligent Preheating per the manual.

    My question is if Parameter 17 (for thermal bypass valve) should be set to On or Off. It is currently set to OFF and my plumber said that is how they always set things up. Tried calling Navien Tech Support to confirm but they won't answer these types of questions for the homeowner :(. Can anyone here help based on your experience?
