To adjust the brightness and color temperature using the OSRAM DALI MCU TW G2 Control Unit, follow these steps:
1. Adjusting the minimal brightness level (optional):
- Set the lighting to the minimal brightness level.
- Rotate the xxxx slowly clockwise until the brightness increases for the first time.
- Press the rotary xxxx for more than 10 seconds.
- The lights will switch off and on again to indicate that a new minimal brightness level has been stored.
2. Storing a defined activation value:
- Turn on the light and set the desired brightness. For tunable white, set the desired color temperature as well.
- Quickly press the xxxx twice (double click). The light will blink twice to confirm that the activation value has been saved.
3. Deleting a defined activation value:
- Turn off the light by briefly pressing the xxxx .
- Quickly press the xxxx twice (double click). The light will burn at its brightest intensity to confirm that the activation value has been deleted.
4. Store color temperature thresholds (recommended):
- The color temperature range of the DALI MCU TW G2 can be adapted and limited to the possibilities of the connected luminaires.
- To set the threshold for the warmest color (lowest color temperature):
- Rotate the pressed xxxx counterclockwise until the desired warmest color is reached.
- Keep the xxxx pressed in this position for more than 10 seconds.
- The lights will switch off three times and on again to indicate that the new threshold is stored.
- To set the threshold for the coldest color (highest color temperature):
- Rotate the pressed xxxx clockwise until the desired coldest color is reached.
- Keep the xxxx pressed in this position for more than 10 seconds.
- The lights will switch off three times and on again to indicate that the new threshold is stored.
5. Reset minimal brightness level and color temperature thresholds:
- Switch off the light by a short push to the rotary xxxx .
- Press the xxxx for more than 10 seconds.
- The lights will switch on and off again to indicate that the thresholds and the minimum brightness level are reset to the ex-factory settings.
Operation:
- Switching the light on and off: Briefly press the xxxx . The switching direction will change each time the xxxx is pressed.
- Increasing brightness: Turn the xxxx to the right.
- Reducing brightness: Turn the xxxx to the left.
- Increasing the color temperature (cooler light): Turn the pressed xxxx clockwise.
- Decreasing the color temperature (warmer light): Turn the pressed xxxx counterclockwise.
- Simultaneous pressing and turning can also be used for certain functions.
