When brightness is set to 0%, the display turns off for minimal light disturbance. However, the unit includes a smart wake feature:

• If the device detects movement near the control panel, the display will temporarily illuminate at70% brightness.
• If no additional movement or button interaction is detected, the display will gradually fade back to 0%.

The selected mode button and On/Off button will  always remain visible for basic control and status indication even when brightness is set to 0%. This ensures night time comfort while keeping controls accessible when needed.
