Function in the Gira One system:
• Actuator for switching and dimming
• Automatic or manual selection of the dimming principle that is appropriate to the load
• Idle-state, short-circuit and excess temperature-proof
• Power extension using power boosters
• Manual operation of the outputs
• Programming and commissioning using the Gira Project Assistant (GPA) from Version 5.0 (available from 03/2023)
• Encrypted data transmission between the Gira One devices

Dimming outputs in the Gira One system:
• Minimum and maximum brightness can be adjusted
• Switch on at the last brightness value or permanently set switch-on brightness
• Set a switch-on or switch-off delay
• Staircase function (a pre-warning time and pre-warning brightness can be set as an option)

Function in the Gira KNX system:
• Dimming actuator with integrated bus coupler
• Switching and dimming
• Manual actuation of the outputs independently of the bus
• Temporary status display can be activated, link via communication object possible across several actuators
• To simplify configuration, all existing dimming channels can be assigned to the same parameters in the ETS and hence identically parametrised
• Actively transmitting feedback or status messages can be delayed globally after a bus voltage recovery or ETS programming operation.

Dimming outputs in the Gira KNX system:
• Independent switching and dimming of the dimming outputs
• Load type can be specified and dimming principle set: Universal (with automatic calibration procedure), electronic transformer (capacitive/trailing edge), conventional transformer (inductive/leading edge), LED (leading edge) or LED (trailing edge)
• Dimming characteristic curve per channel configurable in time and value range for adaptation to the respective connected load
• Dimmable range can be set: switch-on brightness, basic brightness and upper dimming limit
• Performance on receipt of an absolute brightness value can be set (dimming, brightening, fading)
• Performance during relative dimming up in switched-off state can be set (switch channel on, no reaction)
• Switching feedback: Active (transmitting to the bus cyclically or when there is a change) or passive (object can be read) feedback function
• Reaction on bus voltage recovery can be set for each output
• Block function can be parameterised for each channel
• Time functions (switch-on, switch off delay)
• Staircase light function with advance warning function via time-controlled reduction of lighting or activation of permanent lighting
• Can be integrated into light scenes: up to 16 internal scenes can be parametrised per output
• Delay time for scene retrieval can be configured
• Dimming performance can be set when a new scene is accessed (brightening, dimming, fading)
• Visual feedback when saving a scene
• Feedback of brightness value: Active (transmitting to the bus cyclically or when there is a change) or passive (object can be read) feedback function
• For active feedback objects, the type of update can be set (when the input object is changed or when the feedback value is changed). This allows visualisations to be adapted individually.
