Bayliss XL Automatic Roof Vent - x1 - Automatic Opener - Free Delivery

The opener can be set to start opening at temperatures between 12°C and 24°C. This feature ensures that as the greenhouse heats up, the vents will open wider to facilitate cooling. To adjust temperature settings, users can adjust a threaded screw on the opener to set when it should begin opening based on desired temperature thresholds.
