I use a Herpstat thermostat with the probe centered with the RHP but at ground level. You'll want to play around with what temp setting you use since this is not the hot spot. I used a temp gun to figure out what the hottest temperature was. Took a couple days to get it right.

A thermostat with proportional temp control is preferred, otherwise you'll run the risk of creating some very hot areas under the RHP. Something like the Jumpstart has a 2°F swing on it. So if you have it set to 80°, it basically turns the RHP off until it cools to 78° and then will turn the RHP full blast until it gets back to 80°. I think you'll definitely see temps in excess of 100° below the RHP if you do this.
