Hi
I want to replace my old stat so bought an RT500 which is compatible with my boiler,
I have 3 cables going to the old stat, Blue into Neutral, yellow into live, and red into 3.
My new stat has 3 terminals, Live, Switched live, and earth. the diagram on the unit shows
L to L
N to RL to SL
I'm not sure but would I put the Blue to the SL terminal, Yellow to L but no idea with the red!!!
any advice
many thanks
