CO2/RH/Temp Wall - Obsolete

Available with 0-5/10V analog or BACnet protocol communication
Integrated set-point relay
Optional field replaceable NDIR CO2 and RH elements
LCD with cover included

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 temperature, 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.
