HOME It® Garden automatic greenhouse window opener

HOME It® Garden window opener that automatically opens a roof window in a greenhouse when the temperature goes above a preset level, preventing the scorching of the plants in the greenhouse. The window opener works using a heat-sensitive piston and therefore does not require an electrical connection. The window opener is easy to install and adjust and is particularly suitable if you’re not able to open and close the windows each day, e.g. during holidays or other trips and travels. Colour: black.
