As in the title - are these Danfoss? And can anybody inform me what temperature the numbers relate to otherwise they're bloody useless ( well they are anyway!!) cheers
Drayton have never been particularly good at TRVs IMHO. If you're thinking of changing, go for Danfoss Ras-C2 or Ras-D2 (C2 and D2 have the same internal mechanism, but the D2 looks nicer)
