Danfoss 103e7 timer switch change went wrong

[JonnyCarpenter]

i got a danfoss randall 103e7 to replace a danfoss 103, i replaced it today, i put the new backplate on as the old one looked a bit ropey, i followed the wiring exactly how it was previous, but now the boiler turns itself on when the timer switch is off (making a cringey clunking) and turns off when the timer switch is on. any ideas?

thanks

What have you connected to what.

It should be straight changeover.

L&N to 6-5

Red call to 3 com

blue/black switch live to 1

i have solved the problem now.. boiler neutral was in wrong point.

Why would it be if it worked before
