Help needed wiring up WiFi thermostat.

[Scott2703]

I’ve had a look at the wiring but it has got me confused. I normally undertake DIY jobs myself but this has got me stumped.

My original wiring, I have:
Red L
Yellow SL
Earth
Blue (not connected).

For my new thermostat, it’s got:
L
N
N1
L1
C1&2

any advice would be great.

What do the instructions say?

probably "it's dark inside this bin".
