The E30 digital pressure switch is supplied pre-loaded with a simple program. It

is set to mode 1, loss of prime pressure switch, and it has its startup and run-on

timers both set to 5 seconds. All other functions are turned off and its pressure

set points are all set to zero.

Provided the E30 is unlocked you can restore it to this default state at any time by

pressing and holding down the (P) button and pressing the (R) reset button at the

same time. Release the reset button while still holding down the (P) button and

then release the (P) button. This process is called purging the system and doing

this removes any settings you have entered and restores the E30 to its original

default state.
