L For each zone, the current brightness has to be taught in
with the smartphone/tablet (see chapter 8.4 Parameters,
page 7.)
Constant lighting control
The zones must be arranged in such a way that each indivi-
dual zone only captures its own artificial light. Artificial light
controlled by other zones, or manually switched working
lights, will affect the brightness measurement of the detector.
L Avoid direct artificial light.
Switching mode
If the brightness measurement is deactivated, the lighting is
only switched depending on presence.
6. Functions
Light
The optical presence detector switches or controls 6 ligh-
ting groups depending on the presence of persons and the
current brightness. The brightness switching value or setpoint
is set via parameters or objects (with objects only brightness
setpoint).
Switching
The lighting is switched on when there is presence and low
brightness, and switched off when there is absence or suffici-
ent brightness. A button can be used to manually switch or
dim, which stops the control for the duration of the presence.
In addition, a free switch object is available.
Constant lighting control
When constant lighting control is active, the brightness is
held constant at the brightness setpoint value. The control
is started fully automatically or manually via button. Manual
switching off or dimming stop the control for as long as the
presence continues.
Standby
The standby function serves as an additional delay after the
motion time delay has elapsed. The lighting will be set to the
standby dimming value (1 – 25%) at the end of the time
delay. The standby time can be set between 1 s and 60 min
or permanently. The lighting is switched off if the brightness
level in the room exceeds the brightness switching value/
setpoint. If the brightness level in the room falls below the
brightness switching value/setpoint, the lighting will be swit-
ched on at the standby dimming value. The standby function
can be activated or blocked via an object.
Button control
The lighting can be manually switched or dimmed any time
via a button. If the light is switched on manually, it will remain
on during switching mode for at least 30 minutes, provided
people are present. Afterwards, it will be switched off if the
brightness is sufficient. If the room is abandoned (before),
the light goes out after the set time delay. With constant
lighting control, the lighting is switched on and the control
is activated. If the artificial light is switched off manually, the
lighting remains off as long as people are present. At the end
of the time delay, the lighting will switch automatically again.
Fully or semi-automatic
The lighting control is either fully or semi-automatic. As a
"fully automatic device", the lighting is switched on and
off. As a "semi-automatic device", the lighting must always
be switched on manually. The lighting is switched off
automatically.
Aura effect
The light accompanies the user to the area where he is at the
moment. The surrounding areas are dimmed to a set orienta-
tion light value.
HVAC
For each detection zone (max. 6 zones) the presence infor-
mation can be transmitted, e.g. for heating, ventilation or air
conditioning control. Each channel has a switch-on delay and
a time delay. The integrated temperature sensor also mea-
sures the ambient temperature and can be used for control
purposes.
Switch-on delay
The switch-on delay prevents instantaneous switching on.
The telegram is sent only on expiry of the switch-on delay,
provided that people are present for this time.
Time delay
The time delay allows a delayed switching off of HVAC devices
and systems after the room has been left.
Room occupancy
In each detection zone (max. 6 zones), persons can be detec-
ted, which allows for anticipatory control, depending on the
number of persons. The predefined 3 thresholds can be used
to control a fan, for example. Corresponding links can be used
to add up the number of persons from different zones.
Threshold switch
The 3 integrated threshold switches allow step-by-step con-
trol, such as the control of a fan.
Visual statistics/evaluations
With thePixa Plug app, heat maps as well as occupancy sta-
tistics can be displayed graphically and time-controlled. The
heat maps can be exported via a .csv file.
The information on occupancy statistics can also be called up
via telegrams.
