3.4 Description of functions
The devices described here can, depending on the device type, be used either as presence and/or movement detector.
The difference between movement detector and presence detector:
The main application of the movement detector is the switching of light when persons are moving toward something. The main application of the presence detector
serves for presence monitoring and makes it possible to switch lighting, heating or similar.
In a deactivated state the movement detector also switches without brightness. In an activated state it operates independent of the brightness.
Both movement detector and presence detector are based on the same detection principle.
However, the detection segments of the presence detector have a finer mesh and can therefore also detect persons that are seated as being present and respond
accordingly. In addition, a presence detector, different to the movement detector, can distinguish between artificial light (which has been activated by it) and natural
light; this makes functions such as constant light control possible, for which the amount of artificial light is added to obtain a certain overall brightness.
Main applications:
• BW: Movement, detection range, detection of walking persons.
• PM: Also activities while seated.

does not only switch lamps but can also dim them. This makes constant light control much more precise and maintains the brightness level in the room at the
desired level. The integrated HVAC function makes it possible to control heating, ventilation and air-conditioning in the respective detection range when someone is
present. This additionally saves energy. Two channels are available for this function. Special comfort is made possible with the integration of the IR remote control
(6010/25-500). The device receives the signals and converts them on the KNX bus. The device also contains an integrated room temperature controller object with
temperature sensor. In addition, the device has numerous general functions (see Description of parameters and objects).
01529.1
offers movement detection with 2 channels, as well as constant light switching. Constant light switching adds light when persons move within the detection
range and the daylight does not meet the required brightness level in the room. For this the device detects the luminosity of the lamps used. As soon as the natural
light is adequate, the connected light sources are deactivated.
The combination of these two functions results in two advantages:
• Energy is being saved since the lamps are deactivated as soon as the natural light has reached sufficient brightness.
• Additional energy is saved since the lights are only switched on when persons are inside the room.
Constant light
Depending on the version, the devices offer various options to ensure that the brightness in the room is maintained at a more pleasant level. There is a difference
between the functions of the constant light switch and the constant light controller. Both functions ensure that the brightness does not drop below a certain level
when persons are in the room. The use of a presence detector is especially practical for work stations in an office, since even small movements are detected.
The constant light switch can switch lamps on and off. The constant light controller can additionally dim lights, to maintain a level that is as constant as possible.
Both functions work in dependence of light conditions and movement in the detection range. The devices can operate either in "Automatic" or "Automatic switch-
off" mode. If automatic switch-off is selected, for example, the light must be switched on manually via a control element. The light remains on as long as movement
is detected and daylight is not sufficient. If no movement is detected, the switch-off delay expires. Only then is an OFF telegram sent to the bus via the output. In
automatic mode the movement sensor also takes over the switch-on function as soon as someone enters the room.
