With the programming button.
There are 5 levels(1 to 5) you can set it to. From the factory it's set 1, the lowest level.
In order to know which level it's set at, you need to have the buzzer connected.
Press and hold the programming button. After about 5 seconds it will beep once for level 1. Continue pressing it to hear 2 beeps, then 3 beeps and so on... release it when it's at the level you want.
Setting the closing force is the same way except you need to close the frunk latch before programming it.
Since you have your hands on the controller, bag it. The controller is NOT weatherproof. You need to cover it to protect it from moisture.
