3 binary inputs for connection to conventional switches, buttons and motion detectors with zero-voltage contacts.
The inputs are used to control Gira One actuators or to record status information.
Connection to an external temperature sensor at input 3.
Programming and start-up with the Gira Project Assistant (GPA), from version 5.0.
Encrypted data transfer between the Gira One devices.
Switching functions
NO contact or NC contact operation.
Setting of a switch-on or switch-off delay.
Staircase function; a pre-warning time can also be set.
Parameterisation as a switching function for lights or socket outlets, a garage door function or a door opener function, for example, as well as a switching contact for transmitting the heating requirement to a heat pump.
Garage door function: The time for closing the relay can be parameterised.
Door opener function: The time for closing the relay can be parameterised.
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 movement and presence detectors with zero-voltage relay outputs.
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.
Configurable switching inputs that can be independently parameterised.
Recording and comparison of temperature values via remote sensors (see accessories) at input 3.
Function in the Gira KNX system
Switching electrical consumers via a relay contact.
Device has three inputs with a common reference potential.
Reading in switching states of installation switches or push buttons and other zero-voltage contacts at inputs 1 to 3.
Signal analysis of dew and leakage sensors (see accessories) at inputs 1 to 3.
Recording of temperature values via remote sensors (see accessories) at input 3.
Up to 8 independent logic functions for implementing simple or complex logical operations.
Actively transmitting feedback or status messages can be delayed after a bus voltage recovery or ETS programming mode.
Bistable relay.
Switching functions
NO contact or NC contact operation.
Central switching function via up to 6 switch objects (ON, OFF, permanently ON, permanently OFF).
Switching feedback: Active or passive feedback function.
Reaction in case of bus voltage failure or bus voltage recovery can be set following an ETS programming process.
Logical linking function.
Block function or forced setting function can be parameterised.
Extended blocking function with acknowledgement option.
Time functions (switch-on and switch-off delay, staircase light function – also with advance warning function).
Integration into the light scenes possible: Up to 64 internal scenes can be parameterised.
Scene memory function: Additional visual feedback.
Extended scene retrieval (toggling of scenes).
Elapsed operating time meter can be activated.
Input monitoring for cyclic updating of the switching object with safety position.
