Should a 'H' with a number be shown the display, for example 'H02' then the delay start has been activated. The number indicates in how many hours in the future, the machine will start. So in our example the machine will switch on by itself in 2 hours time. You will not be able to use the machine instantly unless you cancel the delay start. The machine can be programmed to come on up to 24 hours in advance. To re set simply press the delay start button found on the option button cluster repeatedly until 'H0' appears. The machine will now commence the cycle when you press the start button.
