You've done really well. I admire your persistence to get to the bottom of this system that I found really hard to re-engineer and getting it working was not easy without air con.

At 3:50-4:00’sh I describe it the wrong way round. When I put the fan on the flap opens to allow fresh air in when I turn the fan off it closes. It’s actually opening and closing against something behind the flap that isn’t visible.
