2.3 - Read mode

- Connect the console to the VARMECA 20 RS 232 socket.
- Power up the VARMECA 20.
- On power-up, the console display is positioned on the 1st
parameter P01 F-MIN.
The 1st line of the display indicates the parameter
description.
The 2nd line indicates the parameter value and its unit of
measurement.
The key scrolls through the parameters.
The key is used for scrolling in the opposite direction.
