The RH in the room is 65% at 65 degreesThe rest of the house is 35% RH at 65 degreesWhy is there so much humidity in the converted attic roomWe have plenty of ventingWe have forced hot airCould it be possible the heating vent is introducing all of the extra humidity? We tried a dehumidifier and it solves the problem by removing the extra humidityI would like to know the source and get rid of it (if I can) instead of running the dehumidifier 24/7 during the winter.

Yes You Need To Becareful With That!
Condensation occurs when cold surface meets warm airPicture a cold glass of ice water on a hot dayThings need some fresh air circulationYour attic room was possibly an afterthought and retrofitted improperlyThere should have been a space left between the roof and the ceiling for air which would include a vapour barrier on the warm side and insulation next to the sheetingThe solution is to remove the improperly installed interior ceiling and re-install a new one over a well vented and insulated roof/ceiling.
