yesterday i disconnected room stat , cylinder stat , 3 way valve , pump , one at a time and each time boiler still runs on its own....i have heard glow worm pcb s are not very reliable...i guess i'll have a look at that.... incidentally cos the neons light up glowworm troubleshooting says its ok

don't have a frost stat but will start going through the wire jungle eliminating individual components :?

thanks...but i dont think so....its only a couple of months old and i can hear it motoring

I found my house getting very hot and discovered that the ch pump and boiler( gloworm ) were running with stat turned down and even controller switched off.. any ideas ??
