QUICK MENU FOR VARIABLE DISPLAY
(READ-ONLY)
During the start-up of the system it may be useful to easily check the reading of the various probes
or some values in order to follow-up or optimise the process. To access the quick variable display
menu, press and hold the DOWN (

) and STANDBY keys for more than 3 seconds.
Within this menu the up or down arrows allow the display of the variable label. Pressing the Set
key toggles the display of the label with its value (to make reading easier, pressing the set key
alternates between label and value: it is not necessary to hold down the set key). When the label
value is displayed, pressing the up or down arrow will still display the label after or before the
current one (leaves the value display to display the label). The leaving from this menu takes place
automatically after 2 minutes of keyboard inactivity or by pressing up arrow + down arrow.
