when switching the central heating on the boiler doesn't fire but when the hot water is switched on boiler fires and heats water.
The light does come on the control panel when the central heating is switched, just doesn't fire.
Any ideas?
i've connect it up and it works fine except the light is very dim, i'm using a 40w bulb, have tried a 60w bulb and still very dim when turned on full. is the dimmer switch underloaded, do i need to change to a 250w one?
thanks
