So you want to know how to set the BPM with PNW but you don't own that module yet since it's in your bottom row ? Just asking because setting the BPM with Pam's is litterally the module's default screen as well as the very first thing explained in the module's Getting Started section of its user manual...
When initially powered on, Pamela’s NEW Workout’s display shows the current clock tempo setting in beats per minute (BPM). Clicking and then twisting the main blue program knob highlights and then adjusts this BPM value between its maximum and minimum values when turned. Clicking again deselects.
