Normally the horizontal position is open, angled down about 70-80 degrees is closed.


You don't say what this duct is to - or why it would be open in one season or closed in another. In modern systems the same fan in the furnace is used to move both heated and chilled air, so any dampers are only to control the amount of airflow to different zones.


If you have separate A/C, like a mini split system or a system with its own ducting, then maybe this is designed to stop airflow through the heating ducts, in which case you would want it closed in summer. But could be for something else, you would probably have to ask your Heating and AC contractor whatto do at your upcoming Fall cleaning and furnace servicing.
