If you want to make things way simpler and impossible to forget to set the pressurization to airport elevation prior to descent, here's what I do-
Granted, it's not the ''proper'' way however the B100's I fly can't max the differential since they leak (age I guess) Check yours to see if you stay in the green before making a habit of it so you're not bouncing off the safety valve all time.
During climbout, after takeoff checks, in cruise, before descent....whenever doesn't really matter, Set destination airport (taking into account barometric pressure) + around 500' in the control panel. Don't bother setting 1000' above cruise if your plane won't maintain max diff.
For the climb, I set the rate knob fully closed (turn knob left) Before the descent I'll open it slowly to give me the rate of descent I need not exceeding 500FPM.
There you go.
easy, safe and simple.
