KNX MicroFL Presence detector

The range of Eelectron mini presence sensors suitable for ceiling mounting consists of 2 versions: one with a round lens (PD00M01KNX) and one with a square lens (PD00M06KNX). Both are available in a white or black finish and are suitable for mounting up to 4 m in height. These versions also include a brightness sensor for controlling ambient lighting.

Presence detection, based on a passive infrared sensor, has 5 independently configurable channels with different functions that can be activated: presence with or without brightness control and with automatic or semi-automatic detection; constant brightness independent or presence dependent with automatic or semi-automatic activation.

Moreover, 8 logic blocks are available to implement simple expressions with logical or threshold operator or complex expressions with algebraic and conditional operators; It’s possible to use predefined algorithms as proportional controls of temperature and humidity or dew point calculation.

The device integrates the Virtual Holder Logic, designed for hospitality applications, which enables advanced and reliable management of occupancy information within the room. The logic is based on acquiring the status of a magnetic contact installed on the door and connected to a digital input, combined with the processing of data from one or more presence sensors. The combination of this information allows the system to consistently infer the actual occupancy of the environment, detect unexpected presences, and distinguish between different occupant behaviors, ensuring more accurate management of occupancy states.

The device manages the ambient lighting based on the measured illuminance; it is also possible to enable the logic called “Circadian Rhythm” with which brightness and color temperature are imposed on the basis of predefined curves or on the basis of the real position of the sun during the day with respect to a terrestrial coordinate. This function allows you to recreate lighting comfort in an environment as close as possible to reality.

The measurement of lighting in the environment is carried out indirectly and it is therefore necessary to carry out a calibration. The sensor is installed on the ceiling and the detected brightness may differ significantly from that of the work surface; using the ETS® and DCA (Sensor Calibration Tool) software it is possible to set correction parameters for the device basing on a local measurement using the lux meter.

Avoid direct sunlight or artificial light radiating the sensor directly.

The sensor allows different sensitivity levels to be set; carefully read the following notes for device installation and sensitivity settings parameters.

The sensor detects the difference between ambient temperature and temperature of moving objects and people; the lower this temperature difference will be, the less sensitive the sensor will be.

To ensure correct coverage of the sensor surveillance area, prevent walls (even glass) or furniture from being an obstacle; if this is not possible increase the number of sensors in the area in order to have a complete coverage.

Always mount the sensor on a stable surface, not subject to vibrations or oscillations that can simulate movement.

Lighting devices placed near the sensor or in the monitored area can cause false readings, avoid this interference as much as possible.

In the coverage area avoid appliances that produce heat such as fan coils, printers, lamps, etc. . or objects that can move due to wind or air currents.

The device can be configured via the ETS application program and can communicate with the KNX® Data Secure protocol. The KNX communication interface is included.
