Threw a load of mixed colors in the Tag and selected warm wash. Since my OCD makes me watch what it does I was surprised at how it makes "warm". I've been used to "warm" setting mixing the hot and cold together and then dropping hot if it exceded the set point. But the Tag does something different and I'm not sure I like it. When I select warm it will start to fill with hot water then switch to cold and back and forth. I guess the outcome is the same as mixing the two steams, but it means that colored items are soaked with hot water. Seems odd to me.
