What are the differences between the various manual modes?

If the device is used as a process / fixed setpoint controller, the controller output level is preset when manual mode is used.
If the device is used as a program controller, a fixed setpoint is given when using manual mode, and the controller regulates to this setpoint.
If the <Exit/Hand> key is pressed while the program is running, a temporary setpoint change can be programmed. This will only be effective for the program run taking place at the moment. After a new program start, the values that are defined in the program editor will apply.
