I used to have it set up like this.. but i found that the hot side was a consistent 92 degrees, but with the RPH on the "cool" side, to get the temp of the air to 80 degrees, it heated up the floor of my cool side to nearly 90 degrees. My BP was stressed because it didnt really have a cool side. Instead, i put the RHP and the heat pad on the same side. That way my cool side's substrate was the proper 80 degrees, and the hot side is about 92. Snake is much happier now.
