Product catalog summary
Overview
The document provides detailed information about a Carbon Dioxide Detector/Controller designed for professional use in monitoring CO2 levels in air ducts. It highlights the features, specifications, applications, and installation guidelines for various models of the device.

Features
  • Real-time CO2 detection using NDIR infrared sensor with self-calibration and a lifespan of up to 15 years.
  • Optional high accuracy humidity and temperature detection and display.
  • Selectable LCD display and dry contact output with preset setpoints.
  • Optional Modbus RS485 communication interface and ZigBee wireless protocol.
  • Available in four types: wall mounted, duct mounted, split, and plug & play.
  • Special design features for ease of installation and operation, including a photosensor for day/night detection and a rotatable probe for duct types.
  • CE-Approval for compliance with safety standards.

Specifications
  • CO2 Sensor: Non-Dispersive Infrared Detector (NDIR) with a measurement range of 0-2,000ppm (default) and 0-5,000ppm (preset).
  • Accuracy: ±60ppm + 3% of reading at 22℃.
  • Response Time: Less than 5 minutes for 90% step change at low duct speed.
  • Power Supply: 24VAC/24VDC or 100VAC~240VAC with a maximum consumption of 1.8 W.
  • Optional temperature and humidity detection with specific accuracy and stability parameters.
  • IP Class: IP30 for protection against dust and water.

Typical Applications
  • Used in office and residential areas for CO2 level detection.
  • Ventilation control and Building Automation Systems (BAS).
  • Greenhouses, plant bins, and CO2 laboratories.

Dimensions & Mounting
  • Duct mounted: Probe length of 139mm, extendable to 209mm, with a diameter of Ø26mm.
  • Wall mounted: Probe length of 69mm with installation holes of 100mm.
  • Split sensor: 2-meter cable connection with a probe diameter of Ø26mm.

Models Guide
  • Various models are available based on sensor installation type, relay dry contact output, communication interface, power supply, and additional features like temperature and humidity detection.
  • Plug and play options are available for wall mounting types with European or American standard plugs.
