AQD 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 APPLICATIONS
The AQD series design allows customization for a sensor that ▪ Controlling ventilation in response to occupancy
meets project requirements for monitoring temperature, CO2 ▪ Facilitates compliance with ASHRAE 62.1 standard for
and relative humidity. The sensor can be ordered as stand alone air quality
temperature, CO2/Temp, RH/Temp or all-in-one CO2/RH/Temp with ▪ Offices, conference rooms, and public assembly areas
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.

FEATURES ORDERING INFORMATION
Customize to meet project requirements Output CO2 RH RTD/TH

▪ Standard LCD and temperature on each device AQD -

▪ Options to add CO2 and/or RH sensing elements
▪ Field replaceable elements for RH Output Type
▪ Available with 0-5/10V Analog or BACnet protocol communication
A = Analog (0-5/10V)
Protocol Version B = BACnet RS-485
▪ BACnet RS-485 ready CO2 Sensor
▪ Auto-configuration wizard detects baud rate and MAC address A = None
▪ Adjustable set-point using button menu or optional 10k slider B = CO2 Sensor
RH Sensor
Analog Version A = None
▪ LCD for easy setup of all parameters (concealment cover included) B = 2% RH Sensor
▪ Programmable set-points for complete control RTD/Thermistor*
▪ Provision to offset CO2 reading A = None G = 10k w/11k
▪ Optional thermistors, sliders and override button C = 100Pt (385) RTD H = 3k
D = 1000Pt (385) RTD I = 2k2
High performance NDIR CO2 element E = 10k type 2 J = 1k8
F = 10k type 3 K = 20k
▪ Selectable auto-calibration mode returns sensor to
baseline values *Add-on RTD/Thermistor not readable via BACnet; Temperature output is
standard on AQD devices, Add-on RTD/Thermistor is option for Analog.
2% RH field replaceable sensor
▪ On-board temperature compensation for RH eliminates temp
coefficient errors achieving excellent measurement accuracy, high
repeatability and offset stability.
▪ State of the art testing facilities. 8-point NIST traceable
certification available—consult factory
