Getting used to our new oven, and all of it's options - which it can take a while to get used to and find in the menu.  I was surprised by the strong fan action coming out from the top of the oven, as our last wall oven didn't do that (which might be why it kept "frying" its control board). Our other surprise was that the Delay Start feature was limited to only 1 Hr.  We are used to leaving in the morning, with the baking coming on about 11 am, so that the casserole is hot and done when we get back for lunch.  Not sure why the Delay Start is limited to just 1 Hr?? But, we were able to use a slow back approach, which worked also.
