While the pool system is running, the Gemini Control Unit continuously analyses water chemistry and turns on the Salt Unit when more chlorine is required. It also monitors pH and adjusts it to help maintain the desired water chemistry.\u003c\/p\u003e\u003cp\u003eThe multi-electrode probe assesses pool water chemistry and determines the chlorine production required from the electrolytic cell. At the same time, the Gemini System controls pH by feeding accurate doses of acid through a peristaltic pump. This automated approach is designed for use with conventional and mineral salt pools and spas.\u003c\/p\u003e\u003cp\u003eFor scheduled operation, the control unit uses a 24-hour quartz-crystal timer backed by a Real-Time Clock. During a power failure, the system keeps time and maintains AutoMode functions without requiring the settings to be re-programmed. The weather-resistant housing is designed for operation in full sun and rain.\u003c\/p\u003e\u003cp\u003eThe injection manifold is positioned after accessories such as the heater and before the chlorinator cell. This arrangement places the manifold within the return-side installation before chlorine is produced by the electrolytic cell.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eContinuous water-chemistry analysis allows the controller to manage chlorine production and pH adjustment.\u003c\/li\u003e\n\u003cli\u003eMulti-electrode probe measures pool water chemistry and supports automatic control.\u003c\/li\u003e\n\u003cli\u003eElectrolytic cell produces chlorine when additional sanitisation is required.\u003c\/li\u003e\n\u003cli\u003ePeristaltic pump provides controlled acid dosing for pH adjustment.\u003c\/li\u003e\n\u003cli\u003eSelf-cleaning function uses electronic polarity reversal to help clear scale from the electrolytic cell.\u003c\/li\u003e\n\u003cli\u003eBayonet probe fitting provides simple twist-lock installation into the injection manifold.\u003c\/li\u003e\n\u003cli\u003e24-hour quartz-crystal timer and Real-Time Clock maintain programmed operation during power failures.\u003c\/li\u003e\n\u003cli\u003eDedicated filtration-pump outlet and two additional outlets provide timed power for the Salt Unit and other pool equipment.\u003c\/li\u003e\n\u003cli\u003eWeather-resistant construction is designed for operation in full sun and rain.\u003c\/li\u003e\n\u003cli\u003eDosing pump squeeze tubes require replacement every six months by a suitably qualified technician.\u003c\/li\u003e\n\u003cli\u003e3 Year Warranty applies to new domestic installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWarranty: 3 Year Manufacturer's Warranty.\u003c\/p\u003e","brand":"Pool Controls","offers":[{"title":"Default Title","offer_id":51045930959095,"sku":"'00112012","price":6175.18,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/poolcontrols-gemini-30-controlled-salt-water-management-system-for-domestic-pools-spas.png?v=1787285294","url":"https:\/\/foundationpumps.com.au\/products\/poolcontrols-gemini-30-controlled-salt-water-management-system-for-domestic-pools-spas","provider":"Foundation Pumps","version":"1.0","type":"link"}
