KNX motion detector Komfort

KNX motion detector – the new generation of Gira automatic control switches

The Gira KNX motion detector Komfort is also used for the on-demand control of different functions depending on the movements of people. In this case, too, functions such as lighting, heating, ventilation, air-conditioning systems, blinds and even scenes can be simply and conveniently activated when a room, hallway, or staircase is entered. In addition to the Standard version, the KNX motion detector Komfort also features a temperature sensor and thus enables the direct measurement of the current ambient temperature.

Thanks to two integrated digital PIR sensors, the KNX motion detector Komfort�offers reliable, error-free motion detector - for normal (1.10 m) and high (2.20 m) installation zones.

  • Wide range with 180° detection angle
  • Brightness sensor and three brightness limits
  • Adjustment of sensitivity
  • On-site operation enables the lighting to be permanently switched on and off
  • Can be used as an individual device, a main unit or an auxiliary unit
  • Convenient control via infrared remote control
  • Easy switching between configured functions
  • Integrated temperature sensor
  • Easy switching between day/night or week/weekend configuration
  • Walking test function
  • Energy-saving optimisation through adaptive delay time


The Gira KNX motion detector Komfort also offers a multitude of functions which make every life more convenient and more energy efficient:

Convenient control via infrared remote control

Settings such as the sensitivity of detection, twilight stage or additional delay time can be conveniently changed with the infrared remote control, which is available separately. In addition, it is possible to switch the Gira motion detector Komfort on or off manually.

Easy day/night switching

The new generation of Gira motion detectors enables simple switching between �different configurations, such as �day/night mode or week/weekday mode. Five configurable function blocks are available for the three operating modes: security light, security light with
switch-off brightness and detector. All function blocks
operate independently of each other. Which function block is active can be automatically switched in the KNX system or manually switched, for example with the Gira pushbutton sensor 3.

Saving energy with the adaptive delay time

The Gira KNX motion detector offers the option of continuously analysing user behaviour to optimise the delay time (transmission delay) independently. The longer the period during which people are detected in the room, the
longer the delay time. If a room is only entered briefly now and again, the Gira KNX motion detectors reduce the
delay time. This saves energy and conserves the light source by preventing unnecessary switching on and off.

Short-term presence function for conference rooms

The short-term presence function is available as an addition to the
adaptive delay time especially for light and climate control in
conference or training rooms. If a Gira KNX motion detector detects motion only briefly, it selects the minimum delay time regardless of the self-taught
adaptive value. As a result, lighting, heating/cooling or ventilation
will not remain switched on unnecessarily if somebody enters
the room temporarily during
a longer conference break, e.g. the cleaning staff or catering service.

Smart on-site operating concept
and cleaning light function

The on-site operation using a touch function on the motion detector enables a light to be specifically switched on or off permanently and enables the deactivation of automatic motion detection. The current operating status
is displayed via corresponding LEDs. If the operating mode "permanently ON" is activated using the button for on-site operation on the device on the top floor, all the KNX motion detectors change to the corresponding operating mode and this is indicated by the
status LEDs lighting up. On arrival on the lower floor, the whole system can
now be switched back to automatic mode again via on-site operation of the KNX
motion detector installed here.

Operating modes

The new KNX motion detector Komfort offers three different operating modes for selection:

Security light

Motion is automatically detected when the brightness falls below a previously set threshold.
When employed as a security light, the device is usually used to automatically control lighting when people move. In this
operating mode, a light
is switched on until motion detection (including delay time) ends.

Security light with switch-off brightness

This operating mode constitutes an extension
of the operating mode "security light" and enables continuous brightness evaluation. A light that is switched
on can therefore also be switched off during detected movements of
people if the ambient brightness is at a particular level. This also saves energy.


When employed as a detector, the device always operates irrespective of the ambient brightness. Feedback telegrams indicate whether people are present in the monitored area or not. In this case, the number of motion impulses within a monitoring period can be specified, which enables the motion evaluation to be adapted to individual
requirements. Movement is only reported when the device has detected the set number of motion impulses.
This application is suitable if the device is to work as a detector for KNX alarm systems.
