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. Customize to meet project requirements ▪ Standard LCD and temperature on each device ▪ Options to add CO2 and/or RH sensing elements ▪Field replaceable elements for CO2 and RH ▪ Available with 0-5/10V Analog or BACnet protocol communication Protocol Version ▪ BACnet RS-485 ready ▪ Auto-configuration wizard detects baud rate and MAC address ▪ Adjustable set-point using button menu or optional 10k slider Analog Version ▪ LCD for easy setup of all parameters (concealment cover included) ▪ Programmable set-points for complete control ▪ Provision to offset CO2 reading ▪ Optional thermistors, sliders and override button High performance field replaceable NDIR CO2 element ▪ Selectable auto-calibration mode returns sensor to baseline values 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 Quality ▪ Industry leading 7-year limited warranty/ 2-year RH element, 3-year CO2 element limited warranties FEATURES AQD - RTD/Thermistor* A = None C = 100Pt (385) RTD D = 1000Pt (385) RTD E = 10k type 2 F = 10k type 3 Output CO2 Sensor A = None B = CO2 Sensor RH Sensor A = None B = 2% RH Sensor Output Type A = Analog (0-5/10V) B = BACnet RS-485 CO2RHRTD/TH ORDERING INFORMATION *Add-on RTD/Thermistor not readable via BACnet; Temperature output is standard on AQD devices, Add-on RTD/Thermistor is option for Analog.
