Inside the PAC controller, there is a knob labeled "Turn on"
Note: Raising turnon moves the range up. So if turns on at 5 PSI and you run 20 PSI... now if you turn it on at 10 PSI.. you'll have at 25 PSI what you had before at 20 PSI. So an increase to the "Initial" control will be required to get you more at 20 PSI.
