ELSNER 70699 Sewi KNX - Combined sensors for KNX, black

The ELSNER 70699 Sewi KNX AQS/TH-D L-Pr sensor is a multifunctional device designed for the KNX bus system, ideal for monitoring and controlling indoor environmental conditions.

General Characteristics

This sensor is made of plastic and available in two colors: white similar to RAL 9003 signal white (edges) and white RAL 9002 gray (cover), and RAL 9005 jet black. Its size is approximately 105 mm in diameter and 32 mm in height, with a weight between 45 and 80 grams.

Installation

The sensor can be installed on the surface, on the wall or on the ceiling, offering flexibility in choosing the position. The IP 30 protection class guarantees adequate protection against the intrusion of solid objects and drops of water.

Integrated sensors

The ELSNER 70699 sensor integrates several sensors to measure various environmental parameters:

• CO2: Measures the concentration of carbon dioxide in the air in the range of 400-10,000 ppm.
• Temperature: Measures the temperature in the range from 0°C to +50°C.
• Humidity: Measures the relative and absolute humidity of the air in the range from 0% to 85% RH.
• Pressure: Measures atmospheric pressure in the range of 300-1100 mbar.
• Brightness: Measures brightness in the range from 0 to 2,000 Lux, with the possibility of measuring and outputting higher values.
• Presence: Detect the presence of people using a passive infrared (PIR) method with a coverage angle of about 94° × 82° and a range of about 5 meters.

Integration with the KNX System

The sensor operates in the KNX system with a nominal voltage of 30 V DC SELV and a maximum current consumption of 10-20 mA. The connection is made through KNX plug terminals. The device supports up to 2000 group addresses and 2000 assignments, and is configurable in S-Mode mode.

Other Technical Specifications

The tolerated ambient humidity is between 5% and 95% RH, non-condensing. The data recovery time after the bus voltage is restored is about 5 seconds.
