works exactly as I hoped. Fully closed at 20 degrees C and fully open over 30. A little bit fiddly to install. Don't use a high speed drill to drill out the rivets. A slower speed battery drill with a 4mm bit is much better. Use rivets to fit the adjustor to the window rather than the self tappers supplied as they are too long. The other end is easy just using the two captive bolts from the manual system. Adjustor screws in or out to adjust but I did have to screw in to the limit. Check at various temperatures and don't forget to remove the cotter pin.

Great!!! A bit fiddly to install but so worth it. Wish we'd added them when we bought the greenhouse a few years back.

Installed auto vent when I built the greenhouse. The unit did not fit right out of the box I had to make some bits to mount it so it can close properly, but once on it works very well, well worth it
Simple and brilliant
