4 Operation

The operation of functions or electrical consumers can be set individual for each device. Two operating modes are used:

- Single button operation: Switching on or off or dimming brighter/darker, e.g. of lighting, takes place alternately when the same sensor button is pressed repeatedly.

- Two button operation: Two sensor buttons next to each other form a function pair. Pressing the left button, for example, switches or dims lighting on or brighter, pressing the right one switches it off or makes it darker.

Operating a function or load

Consumers such as lighting, blinds, etc. are operated using the sensor buttons (2) and such operation depends on the programming of the device.

■ Press a sensor button.
The stored function is executed.

The actuation pulse is relative to the length of touch. Depending on the function, short and long actuations may trigger different actions, e.g. switching/dimming.

Cleaning the device

The device can be blocked for 60 s to prevent unintentional actions from being executed when the glass is being cleaned.

■ Recalling cleaning function by external telegram, e.g. from central
All the functions on the device are blocked for 60 s.
All the status LEDs of the sensor buttons flash.

i Cleaning with a lightly moistened, lint-free cloth, possibly with a mild glass cleaner. Do not use sharp objects or abrasive cleaning agents, e.g. scouring powder.
