The diagram in post #25 shows the stat wiring and the whole of the system. N is there and connects back to permanent 230A N on the 3A fused spur but is not used/connected on my stat, as I said. The stat simply connects L to SL to pass through 230V when it is calling for heat. Apologies if I am...

My current stat is failing so looking for cheap and cheerful and I will be replacing the lot in a year or so, probably with a heat pump solution. I have never lost power for more than a couple of hours as long as I can remember, probably 40 years, and 27 years in the current house. Apologies if...

Please see post #25 for my wiring diagram.

Yes that is what I assumed (I would just use one of the terminals), which leads back to my original question... is this output switching N only or can it somehow switch L instead? I am trying to avoid the GC version as I only have 3 wires to play with so was hoping that the GA version could...

Its a UK non-condensing, non combi, open vented system, with Y Plan wiring like: As you can see, when the the programmer turns on the radiator heating, it feeds 230V live/line to the L terminal on the room stat, which then feeds to the 3 port valve when calling for heat. Once the valve has...

It would be helpful if we could see the internal wiring of the thermostat (I am struggling to find one for any Tuya stat!) Doesn't COM (terminal 3) just connect to OPEN (terminal 4) or CLOSE (terminal 5) depending on if there is a call for heat? So though its labelled "(N)" is there an internal...

Sorry for the 2 years late message, but had to ask... By this do you mean that the new thermostat switches between connecting L to 2 (NC) when no call for heat, and connecting L to 1 (NO) when heat is called for? I ask because it looks like N is being connected rather than L in the link to the...
