What is the procedure for self-optimization of a program controller?

The controller output types must be defined before self-optimization can be started.
When the device is used as a program controller, the <Exit/manual> key must be set to manual mode. Then use the arrow keys to set a setpoint that is close to reality for the process, and confirm with the <Enter> key.
Now press the following keys simultaneously: <PGM> + <Automatic>.
The self-optimization will stop by itself.
It can also be canceled by using the key combination <PGM> + <Automatic>.
