AQW Series Combo Wall Sensors

  • Available with analog outputs or protocol for BACnet RS-485
  • Integrated set-point relay
  • Optional field replaceable NDIR CO2 and RH elements

Applications

  • Controlling ventilation in response to occupancy
  • Facilitating compliance with ASHRAE 62.1 standard for air quality
  • Offices, conference rooms, and public assembly areas

Description

The AQW series design allows customization for a sensor that meets project requirements for monitoring temperature, CO2 and relative humidity. The sensor can be ordered as stand alone temp, CO2/Temp, RH/Temp or all-in-one CO2/RH/Temp with a 0-5/10V analog or BACnet RS485 output. Lower material costs and installation time by combining multiple sensors into a single sensor housing with standard LCD and optional add-on features.
