I saw the data logger charts and the pictures. Conditions like that are unacceptable, and sometimes you just have to say so. Whether the HVAC system is old or new, if the relative humidity makes wild rapid swings and sometimes there is fog and condensate in the room, something is badly wrong and needs to be fixed. What is it doing now that cold weather is on the way? I wish you well in getting the point across to the right people. Jim Ellis
