22 Lighting applications
22.1 Manual switching or dimmed light
The application controls local switching and dimming of lighting in the room. It
is optimized for short response times between pushing the button and the
response by the lighting actuator.
The room occupancy has the following commands available to manually
operate lighting:
● Switch on
● Switch off
● Dimming up
● Dimming down
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 station
● By manual operation (first-time switch on or appropriately configured
button)

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 connected lighting can only be
switched on or switched on to the minimum burn-in value 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.
