Mine is definitely not a temperature controlled model, but I don't have to change the mix between hot and cold each time it's turned on. There's a center dial that is used to control that, and the outer handle turns the water on and off. It looks like the one I linked works the same way, and I notice virtually no change in the water temperature when a toilet is flushed. I doubt the temperature controlled models had been invented yet when I got these over 15 years ago.
