I have a Ferroli Combi boiler, the central heating switch is on "0" and it's still fired up, the "Auto" switch is in the middle of the "Timer" and "P" and the I overrided the timer and reset the boilr but central heating is still on. I can't afford to have central heating on all the time. Please help.

the control knob will be broken on the contiuous position the only way you can turn it off is by turning off the boiler to repair you will have to remove the control knob by pulling it out towards you then inserting a small screwdriver to push out the bit of plastic on the pcb then turn the poteniometer to the left to change to dhw only then get a new knob and fit it in by pushing it in hope this helps

Thankyou. But technically the CH is still on and will it still be burning gas?

Until you can find the cause you could turn the thermostat down.
