Typical Australian mains pressure sits comfortably inside that band.\u003c\/p\u003e\n\u003ch4\u003eWhat happens if a sensor fails?\u003c\/h4\u003e\n\u003cp\u003eEach of the two sensor packs carries a fail-safe detection point as well as its working point, giving four in total. Above that, the supplied mechanical float valve closes the line without needing power or electronics. And QST alarms if any fill runs six times longer than the first one it learned.\u003c\/p\u003e\n\u003ch4\u003eDo I still need an auto shut-off valve on my RO unit?\u003c\/h4\u003e\n\u003cp\u003eNo. AutoAqua documents installation both with and without one, and the wiring differs between the two. The Smart ATO RO controls when water flows, which is the job an auto shut-off valve does mechanically.\u003c\/p\u003e\n\u003ch4\u003eWhy does the water level end up slightly above the top sensor?\u003c\/h4\u003e\n\u003cp\u003eThe solenoid has a minimum run time of about two seconds, and the tubing between the valve and the reservoir drains after the valve closes. Both add a small amount of water after the blue sensor is satisfied. AutoAqua describes this as normal.\u003c\/p\u003e","brand":"AutoAqua","offers":[{"title":"Default Title","offer_id":55242290790691,"sku":"AA0309","price":299.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/autoaqua-smart-ato-ro-auto-top-for-ro-system-3000769-1600.jpg?v=1781836521","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/autoaqua-smart-ato-ro-auto-top-for-ro-system","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
