It is possible to select whether the light output uses motion-detector
logic or presence-detector logic. With motion-detector logic, the
sensor does not switch OFF light in relation to incidental daylight.
With presence-detector logic, lighting is switched OFF if the daylight
component provides a sufficient level of light. Presence-detector
logic is configured with an offset. If the light level measured exceeds
the "switching threshold + offset switching threshold OFF" value, the
stay-ON time is not re-triggered when presence is detected. The
output switches OFF after the stay-ON time elapses.
In example 1, presence is detected at time point t₁ and the light out-
put switches ON. From now on, presence is detected all the time.
The change in light level is determined at time t₂. The light level
increases again as of t₃. The light level measured exceeds the
"switching threshold + offset switching threshold OFF" value as of t₄.
The stay-ON time is only no longer re-triggered from time t₅. Here,
the light level measured is greater than "switching threshold + off-
set switching threshold OFF + offset". At time t₆, stay-ON time has
elapsed and the light output is switched OFF.

In example 2, light output 1 switches ON first (t₁). The change in light
level is determined at t₂. The light level measured then falls below the
switching threshold of light output 2 and switches light output 2 ON
(t₃). The change in light level is determined at t₄ and, with the change
in light level of light output 1, is added to an offset. As of time t₅,
the light level measured exceeds the "switching threshold light out-
put 2 + offset switching threshold light output 2 OFF + offset" value
and the stay-ON time for light output 2 is no longer re-triggered.
The light output 2 switches OFF the output after the stay-ON time
elapses (t₆). The change in light level is determined at t₇ and added
to the offset. As of time t₈, the light level measured exceeds the
"switching threshold light output 1 + offset switching threshold light
output 1 OFF + offset" value and the stay-ON time for light output 1
is no longer re-triggered. The light output 1 switches OFF the output
after the stay-ON time elapses (t₈).

KNX Application Description for Control Pro Series
1.3 Constant-lighting controller output
Constant-lighting control always approaches the light-level setting
from above to select the level of dimming. If constant-lighting control
is active and below the setting, the setting must first be exceeded.
The maximum deviation from the setting is only above the setting.
Consequently, the permissible range in which control is corrected
is only ever between the setting and the setting plus maximum
deviation. This is illustrated in Figure "Constant-lighting control range
corrected".

The starting value for constant-lighting control can be configured as
a fixed or dynamic value. When dynamic starting level is selected,
the sensor tries to switch lighting ON as closely as possible to the
light-level setting.
Note: the Teach cycle must take place before the dynamic starting
value can be used. The fixed level is used until calibration has taken
place.
A number of parameters can be configured in two different ways for
switching between day/night operating mode.
1.3.1 Calibration
The accuracy of constant-lighting control can be enhanced by in-
cluding the current dimming level during the teach-in process. Dur-
ing the teach-in process, it is important to ensure that the maximum
daylight component does not exceed 20 lux.
After the teach-in process for the light-level setting, lighting comes
on at 100% output and reduces to 0% in 10% steps.
As better compensation for daylight, a correction factor is used
which provides the basis for calculating a correction intensity:
Correction intensity = current dimming level − dimming level on teaching
New light level = current light level × (1 + correction intensity)
Note: if the light-level setting is changed after calibration, calibration
must be repeated for the new light-level setting.
1.3.2 Calibration procedure
1) Deactivate (disable) constant-lighting control and wait for lighting
to warm up (light level measured at lux meter remains constant)
2) Manually dim lighting until the chosen light level setting is
reached.
3) Send a "1" to the teach communication object.
4) The sensor starts calibrating. Duration approx. 110 seconds
