Wireless room thermostat query

[Corbs]

any cable goes in that boiler must be H/R cable .

depends if it goes inside the combustion chamber eg vaillant then i would agree but as its a worcester cdi the op will be ok to use normal rated cable as it wont go above 30 ish dc

Fortunately, non of the wiring goes through the closed/sealed section of my boiler. At least no wiring that I need access too. I’ve checked and it’s all accessible and runs under the boiler unit into and out of the front panel. The biggest pain would be removing the existing cable run to the old room stat.

Thanks for all the comments and advice guys.

Take a permanent live and neutral to the receiver. Link the second L in the reciever to terminal A. Then terminal B to Lr in boiler.
Remove the link in the boiler

Or do what buzz said didnt see his comment before posting

That is not in accordance with manufacturers instructions and can result in problems with the warranty in the future.

My answer would be either.
Since both L terminals are linked it does not matter which is used.

Thank you all for your input and support. Job completed, working a treat (so far) and old unsightly thermostat n wiring removed.
All the best.
