Hi, I am looking to change my thermostat from an existing T6360B wired installation, to a T3R receiver module.
I would like to double check the wiring before I make the change.
T6360B is currently wired as:
T1 - Red - L
T2 - Blue - N
T3 - Yellow - switched?
Tearth - earth

I believe the T3R receiver needs to be wired installation basic configuration -
Blue - N
Red - L
Loop a wire from L to A
Yellow - B

Would be great if someone can confirm or advise.

Depends if the red is permanent live or not, which is really a requirement of the T3R
