I continue to get a popup box OK to Turn Off Camera Cooler? when my sequence ends. Is there a way to cause a warm up and then shut off the camera and cooler?
yes - it is in the equipment profile, there are a few camera options that allow it to warm up and cool down over a period of time. What you are doing I imagine is shutting down before the warming up has concluded.
Yep you can also access it in the control panel and turn it on or off during the sequence if you want to. I think the check box is in the lower left corner "warm up after sequence completes" of the camera tab.
