The application switches lighting on and off based on occupancy of people in the room. The presence detector switches to the state occupied when movement is detected. The time between two movements is bridged with a presence detector delay off. Each movement detected by the presence detector restarts the delay off presence detector.

The room occupancy has the following commands available to manually operate lighting:

  • Switch-on
  • Switch off
  • Dimming up
  • Dimming down

Manual operation using the presence button

The presence button is used to establish occupancy in a room. It is used in place of a presence detector. Establishing occupancy with a presence button is not automatic, but rather the result of a user action. When entering the room, the user switches to "occupied" using a presence button. When exiting the room, the user switches to "absent" using the presence button.

Manual operation overrides automatic

Manual operation by the user can override any existing automation in the room. Any manual operation must be released to return to automatic mode.

DXR2 applications have the following methods to this end:

  • A central scheduler program
  • Presence detector detecting non-occupancy
  • Central commands from the management platform
  • By manual operation (first-time switch on or appropriately configured button)

Burn-in function

Each lighting application function possesses a burn-in function for newly installed fluorescent lights that must be burned in. This ensures that the lights achieve their maximum brightness and life expectancy:

  • T5 fluorescent lamps require a burn-in time of 100 hours.
  • T8 fluorescent lamps require a burn-in time of 20 hours.

Refer to manufacturer data on fluorescent lights for more detailed information.

You cannot dim fluorescent lights during the burn-in period. You can switch off fluorescent lights during the burn-in period.

The burn-in function ensures that newly installed fluorescent lights are not dimmed during the required burn-in period, either by a control algorithm or manual dimming. The minimum actual value for the lighting output is set to the minimum burn-in value. As a result, the user can only switch on or switched on to the minimum burn-in value connected lighting during the burn-in period.

As soon as the hours of operation counter reaches the required number of hours for burn in, the minimum value of the output lighting (BACnet Property Minimal Actual Value) is set to the value OpMinVal; the maximum value of the output lighting (BACnet Property Maximal Actual Value) is set to the value OpMaxVal.

Prewarning during switch off

Each lighting application has a prewarning function. When enabled, the prewarning function does not immediately turn off lighting when the push button is manually pushed. The light blinks in advance for a defined period. The room user can permanently turn on the light again by pressing the button during the prewarning function.

Runtime totalizer

Each lighting application has an operating hours counter. It indicates the time the light was switched on since the last time the counter was reset. Always manually reset the counter if exchanging luminaires. You can reset the counter via central operation or on the DXR2 web server.

Control of state LED

The DXR2 can control KNX PL-Link push buttons or room operator units with integrated LED state displays. The following state displays can be configured:

  • Always off:
  • State LEDs are always switched off on push buttons/room operator unit.
  • Lighting on:
  • The state LEDs for the push buttons (switch off/darker) are switched on if the lights are switched on.
  • Lighting off:
  • The state LEDs for the push buttons (switch on/brighter) are switched on if the lights are switched off.
  • Manual operation lock:
  • All state LEDs are switched on if the push buttons/room operator unit is locked for manual operation.
  • Lighting on, or manual operation lock:
  • The state LEDs of the push buttons (switch off/darker) are switched on if the lights are switched on and all state LEDs are switched on if manual operation is locked.
  • Lighting off, or manual operation lock:
  • The state LEDs of the push buttons (switch on/brighter) are switched on if the lights are switched off and all state LEDs are switched on if manual operation is locked.
