Automatic Greenhouse Vent Opener: A solar heat sensitive mechanism opens and closes a roof window as temperatures change, helping reduce trapped daytime heat and maintain airflow for plants.
Solar Greenhouse Window Control: Operates without wiring or a separate power source, using temperature changes to manage roof vent movement during daily greenhouse use.
Adjustable Temperature Range: Set the control between 68 and 77°F; the roof window responds to temperature changes to help manage daytime heat around greenhouse plants.
Size and Load Fit: Aluminum alloy unit measures 12.6 x 3.74 x 1.97 inches, opens a window up to 18 inches, and supports window weights up to 15 lb; check fit before mounting.
Frame Mounting Options: Clamp or screw the unit onto the greenhouse frame and use it with a roof vent that can move freely; confirm clearance for the window opening before setup.
