I also have a T10, with a Pro-Products RHP. And, I'm using a HerpStat controller. Bob from Pro-Products had always recommended putting the probe on the cool side. I don't think there's a right or wrong location for placement, I just think you have to go with what works best for YOUR situation. For me, the way Bob suggested works very well. I initially did it with a T8, and then a couple years later got a T10. Now, both the T8 and T10 are set up like this.
But, wherever you set the probe, its good that you are doing a trial run. You're going to want to see what the temps are all around the enclosure... and make sure the coldest spot isn't TOO cold, and the hottest spot isn't TOO hot. A temp laser gun works great for this. In MY case, the probe was set on the cool side, a few inches off the ground on the back wall (see pic). I let it run for few weeks always moving the probe and testing. But... basically, with the probe where I have it, whatever I set it to, there's a 10-13 degree difference from the cool side to the hot side. So... for my bp, the t-state is set to 78 (cool side). The hot side (the bottom) gets to about 90. As I go up (as would be the case with a shelf which I don't use) it gets a little hotter as well. But, my girl is rarely higher than the floor (in MY case).
Also... the temps in your room might affect it as well. For me, my snakes are in the basement, and it gets as cold as low 60's sometimes. That's the ROOM, but the enclosure will never hit that.
