I have recieved new PIR Motionsensors from GHI today, and they work really well, thanks for swapping them.
I am investigating the modules, and there is no indicators on the new revision as to which of the potmeters adjusts the sensitiviy and which one is time. Furthermore, there is a jumper to adjust repeat or single trigger. I have found the required documentation here http://www.elecfreaks.com/398.html
I think you should update the GHI documentation https://www.ghielectronics.com/docs/88/pir-module
