Help wiring a central heating thermostat.
Just need a little reassurance from the collective that what I'm thinking is right before I wire up a new thermostat.
Boiler Wiring Diagram
Terminal 1 of the boiler goes to terminal 1 of the thermostat.
Terminal 2 of the boiler goes to terminal 4 of the thermostat.

Thanks in advance.

Depends on the make of stat, on Honywell stats its normally terminals 1 & 3.
Just check continuity on terminals and turn stat up and down if unsure which are switching.
