Danfoss 103e7 timer switch change went wrong

JonnyCarpenter · 20 Aug 2011

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?
