If extraction fans run too slowly, heat can build up in the grow room. If they run too fast, they may remove humidity too quickly or create unnecessary noise.\u003c\/p\u003e\n\u003cp data-start=\"1557\" data-end=\"1951\"\u003eThe EC1 Fan Speed Controller automatically adjusts fan speed based on the grow room temperature. As temperatures rise, fan speeds increase to remove heat. When temperatures drop, the fan slows down while maintaining a minimum airflow level. This ensures consistent ventilation, helping maintain stable temperature and humidity levels that support strong vegetative growth and healthy flowering.\u003c\/p\u003e\n\u003cp data-start=\"1953\" data-end=\"2085\"\u003eMaintaining stable airflow also improves CO₂ exchange and supports better nutrient uptake in hydroponic systems, coco or soil grows.\u003c\/p\u003e\n\u003ch3 data-section-id=\"1qw4ccu\" data-start=\"2087\" data-end=\"2101\"\u003eHow to Use\u003c\/h3\u003e\n\u003col data-start=\"2103\" data-end=\"2644\"\u003e\n\u003cli data-section-id=\"1ahbtzy\" data-start=\"2103\" data-end=\"2203\"\u003e\n\u003cp data-start=\"2106\" data-end=\"2203\"\u003eConnect the \u003cstrong data-start=\"2118\" data-end=\"2136\"\u003eEC1 controller\u003c\/strong\u003e to your EC fan using the supplied \u003cstrong data-start=\"2171\" data-end=\"2200\"\u003emale-to-male active cable\u003c\/strong\u003e.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1xoqnzl\" data-start=\"2204\" data-end=\"2293\"\u003e\n\u003cp data-start=\"2207\" data-end=\"2293\"\u003eEnsure the fan uses compatible \u003cstrong data-start=\"2238\" data-end=\"2290\"\u003eSystemair EC active cables with white connectors\u003c\/strong\u003e.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1iz42br\" data-start=\"2294\" data-end=\"2382\"\u003e\n\u003cp data-start=\"2297\" data-end=\"2382\"\u003ePlace the \u003cstrong data-start=\"2307\" data-end=\"2328\"\u003etemperature probe\u003c\/strong\u003e at canopy height within the grow tent or grow room.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"fb3e3n\" data-start=\"2383\" data-end=\"2453\"\u003e\n\u003cp data-start=\"2386\" data-end=\"2453\"\u003eUse the temperature dial to set your desired maximum temperature.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"fph7cp\" data-start=\"2454\" data-end=\"2540\"\u003e\n\u003cp data-start=\"2457\" data-end=\"2540\"\u003eAdjust the \u003cstrong data-start=\"2468\" data-end=\"2507\"\u003eminimum and maximum fan speed dials\u003c\/strong\u003e to define the operating range.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"cczifn\" data-start=\"2541\" data-end=\"2644\"\u003e\n\u003cp data-start=\"2544\" data-end=\"2644\"\u003eThe controller will automatically increase or decrease fan speed to maintain the chosen temperature.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp data-start=\"2646\" data-end=\"2793\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eFor systems running both intake and extraction fans, the EC1 can be used with an \u003cstrong data-start=\"2727\" data-end=\"2754\"\u003eActive Y-splitter cable\u003c\/strong\u003e to control two EC fans simultaneously.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/article\u003e\n\u003c\/div\u003e","brand":"Hydro Crop Shop","offers":[{"title":"Default Title","offer_id":52712483324170,"sku":null,"price":72.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/fan-controller-global-air-ec1-fan-speed-controller-29227822579896.webp?v=1773494351","url":"https:\/\/hydrocropshop.co.uk\/products\/global-air-ec1-fan-speed-controller","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
