Been in touch with Danfoss UK and they dont do them,
even though they are made by hago/danfoss, so ringing Delavan in USA, not much help
, rang THERMOBILE (people who make a commercial equivalent of what we are doing on this site) explained my plight, was told nicely to go away
they were NOT going to help,
so once i find someone who can supply me i will propbably buy a few and help out others on this site
