Hi on the motorised valve the blue goes to neutral. Earth to earth . the brown is linked to the demand( send) at the room stat ( should be connection 1 in stat) .
The gray goes to a permanent live. When there is demand from the stat ,saying we need heat the motor in the motorised valve, powers open , operating a switch that sends power from the grey to the orange , and on to fire the boiler . hope this helps , if not let me know and we can go through it .
