You need a very thin and reasonably long PZ2 (IIRC) screwdriver to get the valves open, and to put them together afterwards. I got as far as taking one apart, and haven't found the time (along with all the other jobs) to get any further. I also haven't found a screwdriver thin enough to get it back together !<br>
When you get it apart, it's a neat little board with a row of contact pads - so ideally wants a "bed of nails" jig.<br>
<br>
AIUI the situation is, Damon can correct me if I've got the wrong end o the stick :<br>
Each unit comes with a different security key pre-programmed which Vestimi (ie Damon) can tell you.<br>
The standard OpenTRV code for boiler controller and stats hub only works with one security key at a time.<br>
So you have to open up each valve to set a new security key common across all the valves in the house.<br>
They are working on code for BC/SH to handle multiple keys.<br>
<br>
I'm assuming that if they have the multi-key code ready(ish) then it would work with the existing BC/SH designs.<br>
