Just bought flat and am trying to get to grips with all the stuff. It's got an integrated oven but it seems you can't just turn the temp to 200 deg or whatever and wait till the light goes off to indicate it's reached that heat. You have to put the timer on for the oven to start heating - the light doesn't go on and the fan start working until you do this - is this normal? I think it's a Delonghi
