AQW Series

CO2/Humidity/Temp

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

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 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 ORDERING INFORMATION
standard LCD and optional add-on features. Output CO2 RH SLD BTN RTD/TH Color
APPLICATIONS AQW -

▪ Controlling ventilation in response to occupancy
▪ Facilitates compliance with ASHRAE 62.1 standard for air quality Output Type
▪ Offices, conference rooms, and public assembly areas A = Analog (0-5/10V)
B = BACnet RS-485
FEATURES CO2 Sensor
Customize to meet project requirements A = None
B = CO2 Sensor
▪ Standard LCD and temperature on each device RH Sensor
▪ Options to add CO2 and/or RH sensing elements
▪ Field replaceable elements for RH A = None
B = 2% RH Sensor
▪ Available with 0-5/10V Analog or BACnet protocol communication
Set-Point Slider
Protocol Version A = None
B = 1k (Not valid w/ BACnet)
▪ BACnet RS-485 ready C = 10k
▪ Auto-configuration wizard detects baud rate and MAC address M = 6-26k (Not valid w/ BACnet)
▪ Adjustable set-point using button menu or optional 10k slider T = 200-900 Ω (Not valid w/ BACnet)

Analog Version Push Button
A = None
▪ LCD for easy setup of all parameters (concealment cover included) B = Override Button (Requires thermistor)
▪ Programmable set-points for complete control C = User Push Button
▪ Provision to offset CO2 reading RTD/Thermistor*
▪ Optional thermistors, sliders and override button A = None G = 10k w/11k
C = 100Pt (385) RTD H = 3k
High performance NDIR CO2 element D = 1000Pt (385) RTD I = 2k2
E = 10k type 2 J = 1k8
▪ Selectable auto-calibration mode returns sensor to F = 10k type 3 K = 20k
baseline values Color

2% RH field replaceable sensor 1 = White
6 = Black
▪ On-board temperature compensation for RH eliminates temp
coefficient errors achieving excellent measurement accuracy, high
repeatability and offset stability. *Add-on RTD/Thermistor not readable via BACnet; Temperature output is
▪ State of the art testing facilities. 8-point NIST traceable standard on AQW devices, Add-on RTD/Thermistor is option for Analog.
