Hi Gary, Thanks for taking the time to answer. This is a digital clock with all sorts of buttons round the outside. As the boiler is due for a service soon I have decided to let an engineer reset it rather than risk mucking the whole system up - but thanks again for answering.

Hi Debbie, if this is a clock which is part of the boiler, all you need to do is move the minute hand round once with your finger?
if it is not part of the boiler let me know the model of your timer
