Yes, Mike, you can cook with 2 different temperatures as each oven has its own side of the control panel.
Please see page 28 under "The oven control panel (A, B)," page 31 under " Minimum and maximum settings," and page 35 in the "Twin Mode Temperature setting ranges" section of the manual for more details.
