963 BYV - 1961

Sorry, I didn't see post #4, as I was writing at the same time. Looking at your photo, the thermostat is controlling the actuator of a wet UFH system, rather than powering an electric heating mat. A thermostat with a 3A switching rating *should* be sufficient (depending on your actual system...

It's a switched live output on L1 on the existing stat - no need for any other wires; the neutral (to the load) could be connected anywhere (hopefully from the same circuit). The new stat would simply require a short link wire between L (2) and COM (5). The black wire would then connect to NO...

Sorry, probably not helpful, but may help with troubleshooting.. Since taking the old lock out, have you tested it? If the old eurocylinder moves freely, the issue could have been with the lock mechanism from the beginning.

Two red LEDs... I'm sticking to my original guess :)

"How to build a car", by Newey is well worth a read. It's amazing how much he has achieved; beng one of the last people who has an overview of every aspect of the car, rather than engineers today that due to the vastness of the subject (and through no fault of their own), can only specialise in...

Where's @FrodoOne when you need them? :)

Active/Phase?

Even the MIs aren't clear... I believe (guess!), the indicators show the state of the socket and the second (additional) outlet - edit, in this case the fan.

K's Boxster, obvs! ;) Uh-oh...

Coincidentally, saw LUW1S today on a grey Land Rover.

As far as I know, there is little difference between the receivers, one is simply an update of the other. Whether this has any impact on Zigbee compatibility, I'm afraid I don't know. Similarly, there isn't much difference between the SLT3 and SLT3C - some cosmetic changes, a silver knob...

Over on the plumbing forum, posters who have new builds often want to change their 'stats to smart 'stats. The second heating zone may have a simple battery powered, two wire 'stat installed, but the wiring behind it is 3 core + earth. Several times, the poster has simply taken the spare core...
