A couple of proportional solenoid valves would have solved that

What did he try to do, PWM the hot and cold water?
He wanted to mux cold and hot because he didn't wanted to install another

Maybe he thought of PWMing to get warm water. I don't remember the gory

But he finally got to reason and didn't try it.
He made all of us roar with laughter.
