Room humidity, temperature and CO2 sensor or measuring transducer, in-wall in the panel switch programme, with Modbus connection The room sensor and measuring transducer AERASGARD ® FSFTM - CO2 - Modbus in the in-wall housing, optionally with potentiometer, is used to measure the CO2 content, relative humidity and temperature of the air, and for setpoint adjustment. The measured values are queried via the Modbus interface. Mounting diagram The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). A digital, long-term stable sensor is used for humidity and temperature measurement. R elative humidity [%  R H] is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. 60 The in-wall sensor is mounted in high-quality panel switch programmes, ideally of the brands Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using in-wall adapters, no setpoint adjustment possible) either individually or in combination with light switches, socket outlets, etc. It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, and in interior rooms, such as living rooms, offices, hotels, etc. TECHNICAL DATA Power supply:  Power consumption:  Data points: Bus protocol: Signal filtering: CARBON DIOXIDE (CO2) Sensor, CO2:    24 V AC ⁄ DC (± 10 %) < 4.4 W ⁄ 24 V DC ; < 6.4 VA ⁄ 24 V AC relative humidity [% RH], temperature [°C], CO2 content of the air [ppm] as well as setpoint potentiometer (no setpoint adjustment possible with Busch-Jaeger) Modbus (RTU mode), address range 0…247 selectable 4 s / 32 s optical NDIR sensor (non-dispersive infra-red technology), with manual calibration (via zero button) and automatic calibration Long-term stability:  < 2 % in 15 years 0...5000  ppm Measuring range, CO2:   Measuring accuracy, CO2:   typically ± 30 ppm ± 3 % of measured value Temperature ± 5 ppm   ⁄  °C or ± 0.5 % of measured value   ⁄  °C dependence, CO2: (whichever is higher) Pressure dependence:  ± 0.13 %  ⁄ mm Hg Gas exchange:  by diffusion Warm up time:  approx. 1 hour Response time:  < 2 minutes HUMIDIT Y Sensor:  digital humidity sensor with integrated temperature sensor, low hysteresis, high long-term stability Long-term stability:   ± 1 % per year Measuring range, humidity::  0...100 % RH Operating range, humidity:  0...95 % RH (non-precipitating air) Deviation, humidity:  typically ± 3.0 % (20...80 % RH) at +25 °C, otherwise ± 5.0 % TEMPERATURE Measuring range:  0...+50 °C Deviation, temperature:   typically ±  0.8 K at +25 °C Mounting:  Electrical connection:  Ambient temperature:   Permitted humidity:  Medium:  Protection class:   Protection type:   Standards:  SWITCH PROGRAMME Manufacturer:  in-wall flush box Ø 55 mm 1.0 - 2.5 mm², via plug terminals Storage –35...+85 °C; Operation 0...+50 °C max. 90 % RH, non-precipitating air clean air and other non-aggressive, non-combustible gases III (according to EN 60 730) IP 20 (according to 60 529) CE-conformity, electromagnetic compatibility according to EN 61 326, EMC Directive 2014 ⁄ 30 ⁄ EU GIRA System 55 (other switch programmes, manufacturers, colours as well as prices available upon request) plastic, the standard colour is pure glossy white (similar to RAL 9010) (other colours are available upon request with colour variants depending on the respective light switch programme) www.SplusS.de mail @ SplusS.de Connection diagram
