Could anyone please offer any advice on the wiring positions for the new valve, the old valve has numerous wires so I'm now unsure of the positioning for the new, please see attached pictures, all advice appreciated

There still wired up so remove one at a time and replace them with the same colour

It says the brown and white is the live, does that look right? There are 8 wires on the old one and 4 on the new?

I gather it isn’t standing and you have no WiFi as you haven’t let us know?

House is still standing just about was just delayed in replacing, so I fitted the new part and set it to manual, pressed heating and the boiler fired up which it wasn't doing b4, nothing happened with the radiators so I tried to bleed the pump, I think I managed it as some water came out. Now only one radiator which is closest to the system is Luke warm, I've bled the others with no joy, also the pump it too hot to touch when the system is on. Any advice?
