System information
This device is a product of the KNX system and complies with the KNX directives.
Detailed technical knowledge obtained in KNX training courses is a prerequisite to
proper understanding.
The function of this device depends upon the software. Detailed information on load-
able software and attainable functionality as well as the software itself can be ob-
tained from the manufacturer´s product database.
The device can be updated. Firmware can be easily updated with the Gira ETS Ser-
vice App (additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against
manipulation in building automation and can be configured in the ETS project. De-
tailed specialist knowledge is required. A device certificate, which is attached to the
device, is required for safe commissioning. During mounting, the device certificate
must be removed from the device and stored securely.
Planning, installation and commissioning of the device are carried out with the aid of
the ETS, version 5.7.3 and above.
– Operation in KNX system for Standard and Comfort devices.
– Operation in Gira One system for Standard devices only.
Intended use
– Switching and dimming of
incandescent lamps,
HV halogen lamps,
dimmable HV-LED lamps,
dimmable compact fluorescent lamps,
dimmable inductive transformers with LV halogen or LV LED lamps,
dimmable electronic transformers with LV halogen or LV LED lamps
– Operating in KNX systems
– Mounting on DIN rail according to EN 60715 in sub-distribution unit
If inductive or electronic transformers are connected, observe the data of the
transformer manufacturer on loads and the dimming principle.
HV-LED and compact fluorescent lamps generate high pulsed currents, when
they are operated in the leading edge phase control.
Our dimmers take into account the different electronic characteristics of most
LED lamps found on the market. However, it cannot be guaranteed that in indi-
vidual cases the desired results may not be achieved.
