It is designed to operate within a range of 5°C to 50°C. Generally, it starts to open around 20-25°C depending on the setting, which corresponds to the ideal ventilation temperature for most crops.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eIs it compatible with my greenhouse if it's not an AtmoSerre greenhouse?\u003c\/strong\u003e Yes.

Below this temperature, it remains in the closed position, which is exactly what you want to retain heat in your greenhouse during winter.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow many are needed for a greenhouse?\u003c\/strong\u003e This depends on the number of openings in your greenhouse. For optimal ventilation, we recommend installing one per window or door. For larger greenhouses (from 18 m²), at least two units are recommended to ensure good air circulation.\u003c\/p\u003e","brand":"AtmoSerre","offers":[{"title":"Default Title","offer_id":57580357878105,"sku":"OUVERTURE-AUTO","price":49.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1031\/3574\/0249\/files\/Syst_me_d_ouverture_automatique_pour_portes_et_fen_tres_de_serre_de_jardin_en_polycarbonate_AtmoSerre.webp?v=1777825008","url":"https:\/\/atmoserre.com\/en\/products\/ouvre-fenetre-automatique-serre-sans-electricite-atmoserre","provider":"AtmoSerre","version":"1.0","type":"link"}
