["Raymond Kelly" <raymondtkelly@xxxxxxxxx>]

I've got a Nu-Heat UFH system with 12 zones, and I'm going to retrofit
12 o=
f
the programmable PRTs @ =A350 each --ouch.
I note that he PRT's have a temp sensor in them as well so you can see and
set the temp - good.
What I didn't understand is if there is feedback from these stats

That link with the IP - rs485 http://www.bb-europe.com.  is defo the
way to
go. Read the info last night and it looks pretty detailed and reasonably
priced.
So i'll just connect one to the rs485 bus and away we go.
I have my own embedded linux homebrew so looks like I can send UDP or TCP
packets to control the stats. Now I've just got to do it!!
