Removing a room stat from central heating (in order to fit Hive)
Tackled this at the weekend and my assumptions were correct.

The Centaurstat even has a 'parking' terminal inside (basically a position on the terminal block that doesn't connect to anything) so I moved both the incoming live common and the switched call for heat wires into that parking terminal and all is good.


(Note that the sticker below the terminal block shows that terminal 4 is unused)

When I come to remove the room stat permanently I will need to bridge the corresponding position at the central wiring block.

All good.
