2) | From F 0 press the UP button to navigate to F 1 and press the S key 3 times until the display reads P_1 |
3) | Using the UP and DOWN buttons set display to the setting on the Aagard wiring diagram (Aagard standard setting is 65 psi) |
4) | Press the S key once to display H_1 |
a) | Using the UP and DOWN buttons set display to 1.0 |

System pressure switch settings – P_1 = 65.0
By setting the ISE40A switch up in this manner, the pressure switch will provide an output when system pressure gets to 65.0 PSI; it will loose its signal when it drops below 64.0 PSI.
