Jennifer, we have several different ovens in the test kitchen. At the moment there are three Bosch electric oven sets; 2 have convection fans. The standard double oven pair with has a convection unit on top and the lowest temperature that one will sustain is 170° on the convection setting. Same is true for the Frigidaire double oven set. We have one Bosch side-opening unit that will go as low as 150°; it's an expensive model. When you're doing your homework, you can download the manuals for most models online; then you can find out from the horse's mouth, so to speak, what the lower end of the convection range is for that model. All depends on what they program it for at the factory. Susan
