pressuretrol minium setting 2 psi?

I have a honeywell l404a 1354 Pressuretrol on a Burnham PIN5sns-me2 gas boiler. My pressuretrol has 2 psi as the lowest setting for both the main and diff. It is currently set to 5 psi main 2 psi diff subtractive. There is no dial inside - both adjustments are screws ontop of the gray box.

everything I read says to set 1.5 main, .5 diff. Do I need a new pressuretrol that is more sensitive?

Thanks for the help - Recently realized you can search the wall - I did that but did not see anyone else that had this issue.

    set the main

    at three and the diff at two. This will turn the system on at one psi and off at three. Then you can turn both down equal number of turns to get down to .5 and 1.5. This will take a little bit of trial and error. Once you get it set, mark the dial. The front cover comes off with the front screw. The adjusting screws are on top
