I really don't like anything about this oven..I am a bakery and love to cook.... Your delay should be more than 1 Hour.. All of my oven delay start were up to or more than 8 hour..  when you have both ovens on and would like to shut one oven off the other one turns off also. If you shut down the ovens and then go to shut off the light in the oven, the ovens turn back on. What is the purpose of that. Ever time i use the timer and want to shut the timer down the oven turn back on. Also when you turn the timer off the oven comes on...
