    duct

    where does the duct go,  AHU ?  MA unit,   sometimes these would be installed to try to correct a miscalculation on original design or reheat of new zone that was added.

    There was an error rendering this rich post.

    mixes

    It looks like it mixes return air with outside air and the duct heater is in the outside air duct
