I wrote the heat ramp i want to use in the parameters 60c for 10 hours 70c for 2 hours 80c for 2 hours 90 for 2 hours to cure my mould and can't find how to start the oven ? ' do I need to set the ctrl. method in the control to something else ? thanks I've finally built my oven  and connected it to my spare laptop .
Thanks

On-off will simply ramp up to the set value, it won't run a program. Change the control method to Prog to run programmed ramp rates and dwells.

However, this shouldn't actually stop the oven from starting, the oven should be heating up whenever that 'out1' light is on. Does your oven heat up at all? If not, I'd say theres a wiring issue.

sorted it mate thanks I must have slackend a wire when fitting the wires for the usb adapter.

could you tell me how to do it manually as I want to learn this way as well please.
thanks. 

Hard to explain without writing a novel to rival The Hobbit. Your controller should have come with a manual? If not, it is available online if you Google Omega CN7800 Manual. It's a bit hard to make sense of at first, but its really very simple.
