{"product_id":"sigilventus-smart-pro-ec-fan-controller","title":"SigilVentus Smart Pro EC Fan Controller","description":"\u003cp\u003eWarm afternoons push a grow room past its target, cool nights drag it back, and fans left on one speed spend most of the day running too hard or not hard enough. The SigilVentus Smart Pro EC Fan Controller watches the temperature for you and moves your EC fans to suit. It runs up to four fans at once, intake and exhaust together, and it keeps watch over the fans themselves too: if one stops responding, the controller raises an alert and tells you exactly which fan has failed.\u003c\/p\u003e\u003cp\u003eEC fans take their speed from a dedicated control signal, and this controller is what sends it. A 5 m (16.4 ft) thermal probe reports the temperature in real time, and the on-device screen shows the live status at a glance. There are three ways to run it. Auto Mode raises and lowers fan speed against the target temperature you set. Manual Mode holds one fixed speed, picked from six stepped levels. Alarm Mode alerts you when the temperature climbs past your limit. In Auto, the fans only work hard when the room actually needs it, and they're quieter the rest of the time.\u003c\/p\u003e\u003cp\u003eDifferential pressure adjustment is the other clever part. It lets you fine-tune the air pressure in the grow room to help stop unwanted drafts. Pressure is worth understanding. When the exhaust pulls slightly more air than the intake supplies, the room sits at a gentle negative pressure and air leaks in through the gaps instead of out, which keeps odours contained until they leave through the exhaust. Push the balance the other way and air starts escaping wherever it can.\u003c\/p\u003e\u003cp\u003eThe controller is built for SigilVentus's own EC Fan and EC Silenced Fan ranges. Other EC fans that use the same 3.5 mm (1\/8 in) control jack and control signal may also work with it.\u003c\/p\u003e\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e This controller does not support AC fans, or EC fans that use an incompatible control protocol, such as certain PWM-only models.\u003c\/em\u003e\u003c\/p\u003e","brand":"SigilVentus","offers":[{"title":"Default Title","offer_id":67424454967454,"sku":"0655390356352","price":249.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/SigilVentus_Smart_Pro_EC_Fan_Controller.png?v=1793806136","url":"https:\/\/www.hydrooasis.com.au\/products\/sigilventus-smart-pro-ec-fan-controller","provider":"Hydro Oasis","version":"1.0","type":"link"}
