KNX presence sensor with wall mounting. Standard with brightness control

Lighting NEW

The range of Eelectron presence sensors suitable for wall mounting consists of 2 versions: 1 Standard suitable for mounting up to 4 m in height, 1 HI-BAY (large heights) up to 16 m in height.

Both versions, STANDARD and HI-BAY, include a brightness sensor for controlling ambient lighting.

Technical highlights & Configuration

Core Features

All versions have a rear connector with 3 digital inputs that can be connected to potential-free buttons or switches and used for on/off commands, dimming, shutters or blinds / scenarios, sequences, step-by-step controls, etc. In both versions, one of the 3 inputs can be configured as analog for the connection of NTC temperature probes (see eelectron probes code TS01AxxACC/TS01BxxACC/TS01CxxACC/TS01DxxACC) with which to send the temperature measurement on the bus or manage a complete thermostat module. The thermostat manages 2 stages with integrated PI controller for driving heating and cooling equipment, valves, 2 and 4-pipe fan coils, etc.

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 dependent on presence and with automatic or semi-automatic activation.

There are also 12 logical blocks with which to create simple expressions with logical or threshold operators or complex expressions with algebraic and conditional operators or use predefined algorithms such as proportional temperature and humidity controls or dew point calculation.

Technical Data

The device manages the ambient lighting based on the measured brightness; 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 lighting comfort to be recreated in a room that is as close to reality as possible.

Room brightness measurement is carried out indirectly and calibration is therefore required. The sensor is installed on the wall and the brightness detected may differ significantly from that of the worktop; through the ETS SW it is possible to set correction parameters for the device on the basis of an on-site measurement by means of a lux meter.

Do not allow sunlight or artificial light to shine directly into the sensor.

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

For correct coverage of the sensor monitoring area, do not allow walls (including glass) or furniture to be obstructed; if this is not possible, it is possible to increase the number of sensors in the area to have complete coverage.

Always mount the sensor on a stable site that is not subject to vibration or oscillation that could simulate movement.

Luminaires placed near the sensor or in the monitored area can cause false detections, avoid this type of interference as much as possible.

Do not have heat-producing appliances such as fan coils, printers, lamps, etc., or objects that move due to wind or drafts in the coverage area.

Mounting & Compatibility

The device also integrates the “Virtual Pocket Logic”; The field of application is the hotel room: by means of 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 infer the presence of people in the room using one or more dedicated sensors. It also detects unexpected presence and is able to differentiate multiple behaviors.
