The 'temperature control' is an adjustment to the 'White Balance' setting. You can adjust this on RAW files, before they are converted into image files. But once the conversion is done, the WB setting is applied to the image and you can no longer change it in Photoshop. If you shoot in JPEG, right from the camera, you can't adjust the WB at all. This is one of the advantages of shooting RAW.
With all that said, you can obviously still adjust the colors in Photoshop...and there are many different ways to go about it.
Now, I should mention that with a non-destructive editing program like Adobe Lightroom, you don't actually covert the RAW files until the output stage...so you can change the WB or anything else at any time in the editing process. It really is a revolutionary way to work on digital images.
