On this page we have brought together the most important questions and answers on the KNX building control system.
Constant light control is switched off when manual dimming occurs. Control operation will only be restarted after presence end or a switch-on command to the actuator.
To prevent dimmable energy saving lamps flickering or not activating correctly when switching on, the switch-on will always be 100% followed by dimming to the desired brightness value within 1 minute. Detailed information about this can be found in the DMG 2 S KNX manual.
The LED flashes if no application is installed and the bus address has been allocated twice. When the application is installed, the LED only flashes in the start phase.
The detector works semi-automatically. Application A without button input. Link the buttons directly with the actuator. The response of the actuator to the trigger input of the detector. The light output on the actuator. The light is switched on via the button. The actuator transmits to the presence detector via its feedback object. The detector is working. Switch-off is via the button. The actuator switches off and sends a "0" via the feedback object. The detector goes on working and sends a "0" after the time has expired.
Load the ETS3 update (see website of the KNX Association). Programming this device is not possible with the ETS3 Version D.
Yes. However the basic device must be a MIX2 device. A MIX basic device can only be combined with MIX upgrade devices.
Yes. For this purpose the application V1.6 must be loaded and set in the load setting "Dimmable energy saving lamp".
The central command always affects only the switching object, i.e. only the first object in a switching channel with logic (e.g. Object 0). The inputs for the link (e.g.: object 1, 2, 3) will not be addressed by the central object.
Then the download of the application was cancelled or not concluded successfully. When 230 V is connected the display flashes; without 230 V the display is off completely. Alternatively you can also switch on the LED for the Phys. Adr. with a magnet on the top right of the device.
If you do not use Theben Blinds actuator JMG 4 S KNX with 1-byte positioning objects, alternatively you can use the sun shade function with 1-bit telegrams. In the parameter settings for C3, C6 or C7, select the telegram type "Scenes via 1-bit telegrams". The scenes are defined as follows: Scene 1 = "0" ; Scene 2 = "1" ; Scene 3 = "0" ; Scene 4 = "1".
With a sun shade channel (C3, C6 or C7) as well as the objects "Height %" or "Slat %", the object "up/down" must be linked with the drive actuator. An upwards movement, e.g. when brightness falls below the set threshold, is controlled via the "up/down" object.
We have upgraded out DALI software to version V1.3 and hardware to version 1.8. Efficient approach to applying the latest database version 1.3 in an already existing project, without having to reconfigure the group addresses and parameters.
