I'm probably showing that I haven't yet read enough to get all the
terminology correct, but I'm confused by your response.

I beleive that there are fundamentally 2 systems:

(1) Rev2 board that is a wireless controller for the ELV FHT8V valve (
http://www.elv.de/elv-fht8v-funk-stellantrieb-mit-adapterset.html) and also
uses wireless to another Rev2 board used as the boiler controller.

and

(2) Rev7 board that will sit inside an (modified) eQ-3 valve (as supplied
by Conrad:
http://www.conrad-electronic.co.uk/ce/en/product/1168832/Thermostat-head-5-up-to-295-C-eQ-3/?ref=detview1&rt=detview1&rb=1)
- as referenced from here:
http://opentrv.org.uk/blog/target-date-january-2015/   .  The wireless is
only used to communicate back to the boiler controller.

>From what I (mis?)understand I'm think I'm more interested in the Rev7
system, even if that means waiting for a bit, and would be interested in
helping out with how to get it mounted in the valve if that has not already
been resolved.
