Since you only have one process variable, I would try simply using the output temperature. Adjust the scale to the expected range and use the gain to tune. Then, only if you need to, adjust for BW and CW temp. That's my story and I'm sticking to it. You don't care what BW and CW are as long as your valving can achieve the required mix.
