7 INPUT/OUTPUT MENU
This menu is used to display the state of the inputs and outputs, both digital as well
as analogue.
The rst mask, which is present only in the master card parameters, summarises the
machine status with a graphic indication of the compressor power, input tempera-
ture, master water output and circuit operating status.
