Unlike modern touch-screen controllers, the DO 3001 uses a parameter code system. The manual includes a table of numeric codes (e.g., P01 = proportional gain, P02 = integral time, P03 = deadband width, P04 = sensor type selection). To change a parameter, the user holds a “Set” or “Prog” button, enters a code via arrow keys, and adjusts the value.
