I’m replacing my wiring centre, y plan system, i have 2 3 core cables & 2 4 core cables coming from the wall, the 3 port and cylinder stat are in the cupboard with wiring centre, whats best way to work out whats what coming from the wall, i’ve found the room stat, im assuming boiler, pump and ??

How would i find out whats the pump and whats the boiler?

Thanks

Is the existing not labelled up? Is the pump inside the boiler?

Nope no labelling on existing, pump isnt in airing cupboard so im assuming its in the boiler, boiler is a megaflo 2 system 15 compact.

the room stat is a 4 core, so have 1 4 core, 2 3 core to work out whats what.

3 core is likely the boiler, other 3 core could be pump. Only way would be to trace back or use a suitable tester.
