Sorry for any confusion - when I mentioned the valve being closed, I was referring to the butterfly valve within the control unit that, when open, allows hot air to flow to the cabin - not the exit vents on the bottom of the control unit where the hot air is re-directed when the butterfly valve is closed. The exit vents are closed when the butterfly valve is open, and vice-versa.
