This VBScript fragment can be dropped in most anywhere; it will hold things up until the camera has come down to an appropriate temperature. Be sure, of course, that you turn the cooler on before invoking this code.
In this code, cam represents Maxim DL's camera object. The variable camtemp holds the temperature the camera must achieve before continuing with the script. Util is an object provided by ACP, but its function should be obvious enough that you could accomplish the same thing with other tools.
If cam.Temperature > camtemp Then
Do while cam.Temperature > camtemp
