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.

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.

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.
