The display (1), with its extensive text and graphics mode, is almost self-explanato-
ry, allowing easy operation of the controller.
To change from the overview to the settings menu, press the „esc“ key.
The green status LED (2) lights up when a relay is active, the red LED blinks when
an error occurs.
Inputs are made with 4 buttons (3+4), the functions of which change depending on

If applicable there will be a request for con
fi

tion.
