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 5.7.7 and above.
Intended use
– Switching of electrothermal valve drives for heaters or cooling ceilings
– Operation in KNX system
– Installation in sub-distribution units on DIN rail according to DIN EN 60715
Product characteristics
– Switching operation or PWM operation
– Valve drives with characteristics opened or closed without power controllable
– Valve drives 230 V or 24 V controllable
– Outputs can be operated manually, construction site mode
– Feedback in manual operation mode and in bus mode
– Disabling of individual outputs manually or by bus
– Overload-protected, short-circuit-protected, error message with LED
– Protection against jamming valves
– Forced position
– Cyclical monitoring of the input signals can be parameterized
– Feedback via bus, e.g. in case of mains failure or overload
– Bus connection with standard bus terminal
PWM operation: electrothermal valve drives only have the positions "open"
and "closed". In PWM operation, switch-on and switch-off during the drive's
cycle time achieves an almost constant behaviour.
