The enclosure is very big for a BP that size, so are it's hides, hides provide more security if they are snug and the animal barely fits in them, not to mention that your temps and humidity ready are probably off since you are using dial gauges.
Security with an animal that size is the single most important thing, if it does not feel secure it will not eat.
At that size here is what I would do
I would have him in a 6 quarts tub, with aspen bedding and one plastic flower pot saucer for hide, I provide temps no higher then 86/88 on the warm side, wait a week and offer a live hopper.
In the meantime no handling, no messing around.
Once he eats consistently for you at least 3 to 5 feeding you can start handling shortly.
