    Siemens Smart TRV Valve

    Hi, could anyone point me in the direction of a trv valve adapter that would fit a Siemens, thread: M28 x 1.0 mm? This is the part number referenced in a smart valve pdf which they don't supply 6296/3 EAN: 4011395232583. Also let me know if there is an alternative adapter that I could use. Thanks
