Safe-state mode
The safe-state mode stops the execution of the loaded application program.
Only the system software of the device is still functional. ETS diagnosis func-
tions and programming of the device are possible.
Activating safe-state mode
￭ Switch off the bus voltage or disconnect the device from the KNX.
￭ Wait about 10 s.
￭ Press and hold down the programming button.
￭ Switch on the bus voltage or connect the device to KNX. Release the pro-
gramming button only after the programming LED starts flashing slowly.
The safe-state mode is activated.
By briefly pressing the programming button again, the programming mode can
also be switched on and off in the safe-state mode as usual. If the program-
ming mode is active, the programming LED stops flashing.
Deactivating safe-state mode
￭ Switch off bus voltage (wait approx. 10 s) or carry out ETS programming.
Master reset
The master reset restores the basic device settings (physical address 15.15.255,
firmware remains in place). The device must then be recommissioned with the ETS.
In secure operation: A master reset deactivates device security. The device can then
be recommissioned with the device certificate.
Performing a master reset
Precondition: The safe-state mode is activated.
￭ Press and hold down the programming button for > 5 s.
The programming LED flashes quickly.
The device performs a master reset, restarts and is ready for operation again
after approx. 5 s.
Restoring the device to factory settings
Devices can be reset to factory settings with the Gira ETS Service App. This function
uses the firmware contained in the device that was active at the time of delivery (de-
livered state). Restoring the factory settings causes the devices to lose their physical
address and configuration.
