Pratically
The sensor uses the date and time information that
must be provided by bus; using this information, the
sensor imposes, based on the parameters chosen by
the user, the color temperature of the lamps
considering the contribution of natural external
light entering the room and the current time,
practically which point is now in the circadian cycle.
The following parameters are present in the
"General Parameters" page
KNX PARAMETER
SETTINGS
Date Time Format
DateTime (1x8 Bytes)
Date and Time (2x3 Bytes)
Defines the desired format for updating the date and
time on the sensor.
Timezone is
GMT + Offset
GMT - Offset
Timezone Offset hours
0 .. 11
Timezone Offset minutes
0, 15, 30, 45
These 3 parameters define the time zone in which you
are located (including any offsets <1 hour); as we will see
later, the correct setting of this parameter also allows
you to manage on / off events associated with sunrise
and sunset times for a certain date in a certain position
on the globe (Astronomical clock).
Request time on power
ON
no / yes
Forces the sensor to request the day / hour data on the
bus after a restart.
On the ETS page called "Circadian Rhythm" and in
its subpages you can set the parameters of the light
control.
The first selection to be made requires the choice
between "normal circadian rhythm" and "forced
circadian rhythm".
Some parameters are common to the 2 modes such
as:
KNX PARAMETER
SETTINGS
Elevation curve
wide/fast
normal
narrow/slow
Defines the duration of the transition phases between
sunrise-noon-sunset, wide/fast curve refers to a fast
transition; narrow/slow curve refers to a slow transition.
Output mode
warm/cool lamp
RGB
R+G+B
warm/cold lamp: use when lamps have 2 different
ballasts, 1 per component.
RGB: use when the lamps can manage 1 single
command that imposes the color temperature.
R + G + B: use when the lamp manages the 3 R+G+B
components as separated
Output cyclic send time
from 0 to 2 h
Defines whether there is a cyclical sending to impose
light on the lamp
Output send on variation
from <1% to 7%
Defines what is the minimum difference in brightness
that triggers the setting of a new value for the lamp
The normal circadian rhythm requires to enter in
ETS data relating to the position of the terrestrial
globe (latitude and longitude) whose light
conditions are to be simulated. You can directly
enter the coordinates (expert mode) or use the
simplified setting mode; for example, if you want to
recreate the light conditions present at the equator
in a different place (for example Legnano (MI) - Italy)
you will choose Latitude = "equator" and Longitude =
8.92 (the longitude of Legnano).
KNX PARAMETER
SETTINGS
Latitude
Equator
Tropic of Cancer
Tropic of Capricor
expert
Select a standard latitude or a location of your choice
Longitude
-90 .. +90
Select the longitude of the place where the device is
commissioned
Telegram for Daylight

The change from summer time to solar time and vice
versa is imposed with a 1 bit telegram.
Daylight Saving Time

These parameters define the use of summer time if
present.
