Is the Grundfos the type of circulator that uses a magnetically driven impeller instead of a mechanical connection? If so I bet that little device was detecting the movement of the powerful permanent magnets in the impeller...

A very useful tool

Mine is in my pocket every day, along side the old pocket knife. Great idea.

I think they should be offered with heatinghelp.com printed inside:)
