Hello, turned my boiler off at the fused spur before going on holiday.
got back,turned it on now it won`t turn the boiler on. there is a test button on the boiler for engineers and this does turn the boiler on.
but when i press the overrun buttons for hot water or heating,the programer still says off.when i press the extra hour buttons,the red lights illuminate.
any ideas chaps ?

What's the time set to on the programmer? If correct are the on/off times also correct?

When you turn the fused spur off you're relying on the programmer using it's backup battery which generally doesn't last all holidays!!

If all the time settings are correct and still not working, have another shout and one of us should be able to work it out.
