Just like what everybody else said, just give him some time. You will probably wake up in the morning and say "hey where is the snake?" and he will be fast asleep in the hide.
Major props to your careful husbandry right out of the gate. Your temps and setup sound great. Your setup is a million times better than mine was when I got my BP and probably still is (but not for long, i just built him a fancy new cage and bought him a RHP)
