Grundfos ups2/8 proportional pressure

Matt887 · 25 Mar 2021

Is there a way of telling when on speed 3 whether the pump is on proportional pressure or constant? Have worked through the menu but no obvious way. Thanks

I have same pump, but the manual looks a bit different, doesn't mention "Click" when going between modes. But I think when in proportional mode the symbol which looks like 2 triangles stuck together, should show. Operating instructions attached. Fig 13 should help you sort it.

press and hold for 3 seconds to change from fixed speed to pp/cp.

Constant speed - LED is continuous.
PP - LED short flashes
CP - LED long flashes
