New thermostat doesn't turn on combi boiler

[quality]

Don’t think it will work as you’ve wired up the live to the neutral on the stat

So stat side remove the blue wire

Boiler side remove both and only put the brown wire where the blue wire is

Should work now unless you’ve blown the receiver

Wait wait wait
The Thermostat has 2 blue wires, one in the black wire (the left 2 wires) and one in the white wire (the right 2 wires). Which one should I remove?
The way it's connected now the thermostat turns on, so I'd think the live and neutral are correctly connected no?

Black set of wire sheathed

See above black sheathed wires

Alright so just to make sure, this is what I'm supposed to do:

 

[ShaunCorbs]

Correct that’s it . .

Alright gonna give that a go tonight, I'll let you know

The way Shaun has described will work ( as you have marked up) , in essence using the 240v positive from the thermostat transmitter rather than the feed from the boiler as it was designed to do. Just think how a light switch operates it opens and closes the live (positive) side of the circuit ( or should do if wired correctly)

 

[Spir4]

Well that worked, you guys are geniuses, thanks a million !
Still not clear though why the way I originally connected it didn't work, since that thermostat basically acts like a switch between the 230v supply from the boiler no?

 

[Brambles]

No. The thermostat wired in the way you connected it was delivering 240v across the boiler terminals. Without being tedious, the positive feed to the thermostat transmitter should be taken from the boiler terminal 2 not the mains incommer to the boiler
