I have an xv 90 furnace with comfort R enabled. I was wondering if comfort R works the same way in heat mode as it does in cooling mode. Does anyone know the time that the unit stays on low verses higher blower speeds during the heating mode, and what determines the blower speed. Also, is it recommended to operate the unit in Comfort R mode for heating, or is there a more efficient setting for heat?
