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.

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 cooling-
and 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.
