Button interface, 4-gang Standard for Gira One and KNX

Features

Function in the Gira One system

• Inputs: Connection of zero-voltage contacts such as buttons, switches and reed contacts or smoke alarm devices.
• The inputs are used to control Gira One actuators or to record status information.
• Pulse current to prevent contacts becoming dirty (forming an oxide layer) on the connected contacts.
• Common reference potential for all channels.
• Depending on the variant, two, four or eight independent inputs.
• Commissioning the button interfaces with the Gira Project Assistant (GPA) version 5.2.
• Encrypted data transfer between the Gira One devices.

Binary inputs

• Single and double-surface operation can be configured for rocker buttons.
• Connection of rocker buttons parameterised with switching, dimming, shading and ventilation, scene call-up, staircase (motion detector), floor call with Gira G1, garage door and door opener functions.
• Connection of zero-voltage contacts.
• Convenient group control of switching, dimming, shading and ventilation devices.
• Switching contact evaluation of wind, frost, brightness or rain sensors possible with zero-voltage relay contacts, in order to protect shading and ventilation devices from environmental influences.
• Window contact query and visualisation in the Smart Home App: An opened window will result in the activation of the frost protection heating mode after a 5 minutes has elapsed.
• Door contact query and visualisation in the Smart Home App: An open door results in the raising and locking of the blind or shutter.
• Query regarding a heating/cooling switchover on a heat pump, to allow the current operating mode (heating or cooling) to be forwarded to the heating controller.
• Switching contact display to show contact status in the Smart Home app.

Function in the Gira KNX system

• According to the variant, two, four or eight independent channels that operate as inputs or as outputs depending on the ETS parameterisation.
• Common reference potential for all channels.
• Outputs: Connection of LED. Short-circuit-proof, protected against overload and polarity reversal. Parallel switching of outputs possible, for consumers with higher current requirements.
• Inputs: Pulse current to prevent contact contamination due to formation of an oxide layer on the connected contacts.
• Channels can be activated and deactivated individually.

Possible parameterisation depending on the selected channel function

• Contact type can be set.
• Switching: Command when pressed and/or released can be set (No reaction; Switch on; Switch off; Switch over).
• Forced setting: Command when pressed and/or released can be set (No reaction; Forced active, Switch on; Forced active, Switch off; Forced inactive).
• Dimming and colour temperature: The command when pressed, time between switching and dimming, dimming in different steps, telegram repetition if pressed for a long time and sending of a stop telegram at the end of pressing can be set.
• Blind/shutter/awning/roof window: Command when pressed and command sequence can be set.
• Value transmitter: Data point type, value range and value can be set. As an option, the value adjustment can be activated by pressing and holding the button.
• Scene auxiliary unit: Scene number can be retrieved or switched by briefly pressing the button. If the button is pressed and held, the memory function is executed as an option.
• Short and long button press: Up to two telegrams can be sent to the KNX by pressing a button. The transmission behaviour can be set and the time for short and long actuation can be adjusted. The mode of operation of the channels can be set separately.
• Room temperature controller operating point: The mode of operation (operating mode switch-over, forced operating mode switch-over, presence function and target temperature adjustment) can be set.
• Behaviour after bus voltage recovery can be set.
• Disable function can be set.
• Cyclic transmission can be set.
