1 Application for the KNX MultiLight room controller
KNX MultiLight is a three part room controller designed to be pre-fabricated into
suspended luminaires. The KNX MultiLight node, the movement detector and the user
panel will control lighting, climate and shutters in both closed and open plan offices.
The main functions of the KNX MultiLight are:
Controlling heating and cooling
Temperature sensing
User’s panel for manual control
Relay output for light control
Movement and LUX sensor
For programming and configuration see chapters 3 to 8.
For wiring and installation instructions see chapter 10.
For technical see chapter 11.
2 Introduction
KNX MultiLight is designed to be an efficient room controller system for office, hotels and
other commercial buildings where suspended luminaire are used. The core of the KNX
MultiLight is a demand controlled two-step temperature regulator for separate coolingand heating control.
The functionality of the product can be configured and connected to the rest of the KNX
automation system by using the ETS Tools Software (see www.knx.org)
Example 1 – Heating regulator:
The KNX MultiLight is configured as a two-step heating regulator. The regulator has one
temperature set-point for a room that is occupied and another temperature set-point for
a room that is vacant. Let’s say the temperature set-point for an occupied room is 22°C
and the set-point for the vacant room is set to 19°C. The movement detector mounted in
the suspended luminaire will detect a person walking into the room. The set-point will be
raised from 19°C in standby mode (vacant) to 22°C in comfort mode (occupied).
Example 2 – Lighting:
The KNX MultiLight can turn on and off the luminaire. So, when a person walks into the
room and the temperature set-point is changed from standby to comfort mode, the light
will also be turned on. The light can remain off if the lux level in the room is so high that
the light from the luminaire is not needed.

Example 3 – Ventilation:
The KNX MultiLight can control ventilation for the office space based on the movement
detector and the temperature regulator. The ventilation can be reduced to a minimum
when the room is vacant and the controller is in standby mode. The ventilation system
will be asked to increase the ventilation when a person enters the room.
The ventilation system will usually have a cooling effect for the room because of lower air
temperature in the supplied air. The cooling regulator of the KNX MultiLight can trigger
the need for extra ventilation based the room temperature.
Example 4 – User control:
The KNX MultiLight will usually control the climate and lighting automatically. Occupants
may want to take control over their own environment and change lighting, temperature
and shutters manually. The KNX MultiLight can be fitted with a user panel that will
replace the luminaire pull cord. The panel can give the user temperature control, control
of shutters and lighting control. The temperature setpoint can be adjusted -3°C to +3°C
from the user panel (see Figure 1).

3 MultiLight start-up and general functions
KNX MultiLight can be configured by using the ETS Tools Software. The product database
file for KNX MultiLight can be downloaded from http://www.function.no/MultiLight.
Documentation for the parameters, objects and example configurations can be found in
the chapters below.
The MultiLight controller can be set in learn-mode by pressing the learning-mode switch
on the KNX node or by pressing the learn button on the movement detector. The
locations of the buttons are shown with red circles in Figure 2.
Figure 2 - Learn mode buttons
The red programming LED on the KNX node and inside the lens of the movement
detector will be lit when the KNX MultiLight is in learn mode. The programming LED will
blink when the MultiLight is not programmed (un-programmed node).
The node will check communication with movement detector and panel. If
communication has failed the object “Device self-test status” will be set to “1”.
When the error situation is cleared the “Device self-test status” object changes its value
to 0.
The startup procedure for a unit that has not been programmed with ETS includes
switching on the relay and showing motion detection with the red LED. This ensures that
not programmed units will turn on the light automatically.
Use a small circular object like a paper clip or a bare KNX copper wire to reach the
programming button on the movement detector.

Note: The KNX node includes basic functionality for test and commissioning purposes
that will be removed after the first ETS download:
1. The digital inputs will toggle the relay. Digital input 1 can be connected to an
impuls switch for the luminaire pull cord. Pulling the cord will toggle the light
on and off.
2. Detection of movement is shown by blinking the red LED inside the
movement detector lens.

4 General functions and user panel
The status of the KNX MultiLight is shown by the object “Self-Test status”. For normal
operational nodes this status object is low. If the movement sensor or user panel does
not respond the self test status is set high. The object can be configured to be sent cyclic
[1 to 24 hours].
The KNX MultiLight can be configured without a user
panel, with a standard or extended user panel. The
standard and extended user panel option includes a
temperature sensor, buttons for local adjustment of the
temperature set-point and LED indication of the local
adjustment.
The user panel will also show the status of the
temperature regulator by showing either a red light if
the temperature regulator is heating or a blue light if
the temperature regulator is cooling. The extended user
panel will also include up and down buttons and LED
indication for manual shutter control.
The temperature regulator is not available if the KNX
MultiLight is configured without a user panel.
The temperature sensor can be calibrated from the user panel. The calibration mode is
activated if both the + and – buttons are pressed for 5 seconds or more. In this mode
the temperature LED will start to blink for the calibration setting. The + and – buttons
will increase or decrease the measured temperature in steps of 0.5°C. So, the measured
temperature will be adjusted 1.5°C lower if the -3 LED is blinking. The adjustment has to
be acknowledged by pressing both the + and – button.

5 Movement and LUX level detection
5.1 Movement sensor
The combined movement and LUX level sensor is connected to the MultiLight KNX node
through a 4-wire cable.
The communication object for the movement sensor, object 003 "Movement General",
has the following parameter settings:
Figure 4 - Movement sensor parameter window
1. Recovery time for detection from 1 to 255 minutes. The recovery time specifies
the time between the last detected movement and when the object is set low.
2. Action for start of detection can be ”ON” or “no reaction”.
3. Cyclic sending On commands of "Movement General" can be enabled or
disabled. The cycle time can be between 1 and 255 minutes. 0 disable the
function.
4. Action for end of detection can be ”OFF” or “no reaction”.
5. Separate Movement Local object
The movement detector can be configured with an additional communication
object named “Movement Local”. This object can have the following functionality:
a. Semi-automatic: "Movement Local" object is not transmitted at start of
detection, but will transmitt a ”0” for end of detection. The object can be used
as a turn off function.
b. Full automatic: "Movement Local" object is transmitted both at start of
detection and end of detection. The object can be used to both turn on and off
a function.
6.
(Only visble if “Full automatic” is enabled)
Light dependent full automatic: "Movement Local" object can turn on and off a
function base on both movement and the lux threshold switch (see chapter below).

7. PIR sensitivity can be adjusted from 20 to 100, where 20 is the highest
sensitivity. This parameter is default set to 40 and should not be set lower than
this value without testing for false detection.
5.1.1 Master function ”Movement General”
The “Movement General” can be re-trigged from another sensor like switches and
movement detectors. It is necessary to set the “Write” flag in the object 3 “Movement
General” to make the object re-triggable. Se Figure 5.
Figure 5 - Object flags for re-triggable "Movement General" object
5.1.2 Slave function ”Movement General”
The “Movement General” could be configured with “Slave” functionality. The slave
functionality can be enabled by setting the recovery time and the cyclic sending time to a
lower value than the Master (master detector recovery time or staircase timer). The
reaction at the end of detection must be set to “No reaction”.
5.1.3 Cyclic sending
If the value of cyclic sending is lower than the recovery time, the sensor will not send any
cyclic ON telegrams. If the two values are the same, the sensor sends one cyclic sending
right before the recovery time elapses. The cyclic sending time will not be affected by a
re-trigged recovery time.
It is not possible to re-trigg the “Movement Local” by object. This object can only
be re-trigged by the local movement detector.

5.2 LUX sensor
5.2.1 Parameters
The lux sensor has two communication objects, one for the LUX value (Current Value)
and a threshold switch (Lux threshold switch). The object, “Lux threshold switch", will be
high or low based on the LUX value and the parameters below.
Figure 6 - Lux sensor parameter window
1. High threshold value: If the Lux value goes above this value the "Lux threshold
switch" will be set low or no action (depending on the parameter “Action above high
threshold value”).
2. Hystereses for lower value: “High threshold value” – “hysteresis for lower value”
will give the lower limit for the ”Lux threshold switch”. If the current lux value is
below this value, the Lux threshold switch is set high or no action (depending on the
parameter “Action below low threshold value”)
3. Time delay can be specified both for turning on and off the lux threshold switch.
The time delay can be between 1 and 255 seconds. The value “0” will disable the
time delay.
4. Cyclic sending of the lux threshold switch can be activated with a cycle time
between 1 and 255 minutes.
5.2.2 LUX calibration
The lux level object, “Lux Sensor: Current value (lux)”, can be calibrated by writing to
the object. The raw lux value will be subtracted from the written value and stored
permanently in EEPROM/flash.
Both raw values and the resulting calibrated values are shown in Figure 7. The pink line
is the raw value (V) from the sensor, the blue line is the wanted value (W) set by the
user. The calibration factor is: C=1-(V-W/V)
If the raw value V=1000, and the object is updated with 800, then the calibration factor
will be: c=1-(1000-800)/1000=0.8. See the graph in Figure 7.
The formula for calculating the lux is: Lux=c*V
