KNX PRESENCE DETECTOR MULTISENSOR - LIGHTING CONTROL, TEMPERATURE, HUMIDITY, SOUND SENSOR - BLACK

The range of Eelectron presence sensors suitable for ceiling mounting consists of 4 versions: 3 suitable for mounting up to 4 m height. The STANDARD, MULTI and SPACE versions include a brightness sensor for environmental lighting control, the MULTI and SPACE versions also include humidity and temperature sensors with the relative control algorithms and a sound sensor that can be used in rooms with parts not totally visible to the infrared sensor. All versions have a rear connector with 3 digital inputs that can be connected to buttons or switches free of potential and used for on / off commands, dimming, shutters or blinds / scenarios, sequences, step commands, etc. In the STANDARD, MULTI and SPACE versions one of the 3 inputs can be configured as analogue for the connection of NTC temperature probes (see eelectron probes code TS00A01ACC / TS00B01ACC) with which to send the temperature measurement on the bus or manage a complete thermostat module. The thermostat manages 2 stages with an integrated PI controller for controlling heating and cooling equipment, valves, 2 and 4-pipe fan coils, etc. The humidity sensor (MULTI/ SPACE version) manages the measurement of the ambient relative humidity and allows the control with thresholds and ysteresis of humidification and dehumidification equipments. 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. The BASIC sensor exclusively manages the presence detection. Moreover, 12 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 also integrates the “Virtual Holder Logic”; the field of application is the hotel room: through a magnetic sensor installed on the door and connected to a digital input (also to the sensor itself), accurate presence information is managed. The presence detection solution can deduce the presence of people in the room using one or more dedicated sensors. It also detects an unexpected presence and is able to differentiate more behaviors. 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 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 SPACE version integrates the “Utilization function” which enables functionalities for mapping space status and related usage/availability (eg occupancy index and % of utilization rates) and the “Occupancy function” that detects useful data for the processing of information related to the intensity of the activity of the occupants within the monitored areas (to generate a ‘heat map’ of the building areas). 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.
