Application area and features
- KNX keypad for switching, dimming and shutter control, available with two or four buttons.
- Short press, long press and toggle function per button, plus a key lock that disables operation.
- Relative and absolute dimming, 8-bit scene recall and store, and 1-bit or 1-byte value sending.
- One status LED per button, with display modes such as always on, always off and blinking, interlock groups and adjustable brightness.
- Proximity sensor: the backlight and status LEDs light up on approach or on a button press, and dim off again after a set delay.
- Built-in temperature sensor.
- Programming mode can be started on the keypad, so it stays on the wall during an ETS download.
- Powered directly via the KNX bus, no additional power supply required.
