The display (1), which has extensive text and graphics modes, makes servicing
the automatic controller both simple and almost self-explanatory.
Please press the ESC key to return to the main menu.
The green LED status light (2) illuminates when a relay is switched on, the red
LED light blinks in the event of an error message or when saving information.
Entries are made with 4 keys (3+4) that have various functions, depending on
the situation. The ESC key (3) is used to interrupt an entry or leave a menu.
If necessary, a security question will be displayed which asks if you wish to save
the completed changes.
The function of the other 3 keys (4) is explained in the display that is directly
above the keys; the key on the right is normally used to confirm and select.
