Where to put the cables?
Options
When I took off my functioning thermostat, I noticed the wires are not connected in the way as I know them. I know that the blue cable is generally speaking always the Neutral wire. This doesn’t seem to be the case here (I checked other thermostats, and they are all wired this way). Should I put the blue wire in P1, like the neutral? Or should this one go into NO?
I’ve attached a picture as reference

Hello @LJC18,
If you are asking how to arrange your wires when installing tado°, best is always to follow the instructions provided.
Should you face any issues with your device(s) after installation, please contact tado° support. The article I've linked below explains how to do so.0

Do you have a multimeter? That black wire may actually be simple, representing switched live. So:
Brown is the live feed
Blue is the neutral feed
Black is switched to live when the thermosats is calling for heat. It is dead when not calling for heat. Use the multimeter to check.
This diagram

suggests that black is switched live but please check with a mains tester or multimeter.0
