Black wire into No 3 or No 2


There will be a picture inside or with the new thermostat.
If you just have a 2-wire connection, then the neutral
terminal on the thermostat isn't used (if it has one).
Strictly, the black wire should have a piece of red sleeving
pushed onto it as it's a switched live (although you'll
almost never see this done).
