Desigo room automation has various room operating modes available to efficiently control lighting. The system can, depending on the selected room operating mode, reduce light output in the rooms through the use of automatic light functions. This generally occurs during periods of absence, at night or during holidays when spaces are not occupied.
Four different room operating modes are available that can control, via central functions, management platform, schedulers, presence buttons in the room or other BACnet participants in the system.
With Desigo room automation, the operating modes "Economy" and "Protection" can determine how much light output is automatically reduced. In operating modes, "Comfort" and "Pre-Comfort", lighting control is conversely not reduced using automatic light functions, so that lighting can be controlled to the maximum.
The reduced control for the corresponding operating mode refers to dimmable lighting in the room. Moreover, the reduction to light output does not include manual control of lighting using operator buttons in the room. A room occupant is always able to control the full illuminance.
Room operating modes
Four different room operating modes are available that can control, via central functions, management platform, schedulers, presence buttons in the room or other BACnet participants in the system.
Comfort: The operating mode Comfort refers to a room currently in use (occupied).
Pre-Comfort: The Pre-Comfort operating mode places control for an unoccupied room in a state that can be quickly reset to the desired setpoints for an occupied room.
Economy: The Economy operating mode controls rooms that remain unoccupied for an extended period, for example, at night or over the weekend.
Protection: The building is unoccupied over longer periods in this operating mode (e.g. no renters, factory holidays).
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.

Burn-in minimum value | BrninMinVal | 100 [%] |
Operating phase minimum value | OpMinVal | 0.5 [%] |
Operating phase maximum value | OpMaxVal | 100 [%] |
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.
Description | Name | Default value |
---|---|---|
Prewarning function 0:Disable | PreWarnFnct | 0:Disable |
Prewarning time | TiPreWarn | 60 [s] |
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.
