To be safe I would put a cover on each. I keep the covers on year round for the ones I do not use.
Another question is are all the pipes in the walls insulated enough to go through a hard freeze or do you need to let a little water drip out of the facet? For hot water when I want it I use a circulation pump on a timer. I have it run about 4am and 6am for 15 minutes in the winter so I do not have to worry about the pipes.
