It suits installers who want the pump to adjust itself without tuning on commissioning day. The thermostatic valve mixes primary flow with return water to hold the floor at 20–55°C, and the whole unit bolts onto the manifold.\u003c\/p\u003e\u003ch3\u003eWhy installers use it\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSelf-adjusting pump:\u003c\/b\u003e AUTOADAPT, plus proportional pressure, constant pressure and constant curve settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUp to 7m head:\u003c\/b\u003e from the Grundfos UPM3 Auto 25-70.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eLow-temperature ready:\u003c\/b\u003e 20–55°C suits heat pumps and boilers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArrives pre-assembled and tested:\u003c\/b\u003e ready to bolt to the manifold.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecification\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMixed flow temperature\u003c\/td\u003e\n\u003ctd\u003e20–55°C, adjustable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValve\u003c\/td\u003e\n\u003ctd\u003eThermostatic wax capsule, no wiring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eManifold flow and return bars\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax system pressure\u003c\/td\u003e\n\u003ctd\u003e10 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePump\u003c\/td\u003e\n\u003ctd\u003eGrundfos UPM3 Auto 25-70 130, up to 7m head\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWorks with\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/dualmix-stainless-steel-manifold-assembly\"\u003eDualmix Stainless Steel Manifold Assembly\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/3-4-ball-valve-set-for-blending-valve-pair\"\u003e3\/4\" Ball Valve Set for Blending Valve\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pressure-temperature-gauge-for-ufh-mixing-unit\"\u003ePressure \/ Temperature Gauge for UFH Mixing Unit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/grundfos-replacement-pump-power-cable-upm3\"\u003eGrundfos Replacement Pump Power Cable (UPM3)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eQuestions\u003c\/h3\u003e\u003cp\u003e\u003cb\u003eDoes the blending valve need wiring?\u003c\/b\u003e\u003cbr\u003eNo. It's a thermostatic wax-capsule valve, so only the pump needs power.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAuto or Flex: which Grundfos pack?\u003c\/b\u003e\u003cbr\u003eChoose the Auto if you want the pump to set itself.
