Introduction
Description
The wireless CO
2
+ TRH (Carbon Dioxide + Temperature and Relative Humidity) sensor is a wall mounted device with ambient (indoor) comfort
monitoring and HVAC control applications.
The sensor can measure ambient temperature, relative humidity and depending on the model - CO
2
concentration. The measured data is
communicated wirelessly using ZigBee Green Power protocol to a Room/ Zone controller.
The sensor integrates an ultra-low power CO
2
and a digital temperature(T) and relative humidity (RH) sensor.
The Human Machine Interface (HMI) of the sensor is based on a bi-color Light-Emitting Diode (LED) and a pushbutton, both covered by a plastic
housing. A small tool or stylus is needed to push the button located through a small hole. The LED flashes through the top plastic cover and is not
visible when not active. All communication with the device is done wirelessly via a bidirectional ZigBee Green Power protocol after a successful
pairing/commissioning procedure.
The sensor is powered by an embedded AA size lithium-thionyl chloride spiral battery (not rechargeable, not removable). The battery capacity
allows up to 10 years of operating time at nominal conditions. The device must be replaced and recycled when the battery is discharged.

System Requirements
If used in conjunction with a Schneider Electric Room Controller, the wireless CO
2
+ TRH sensor requires a SE8000 Series Room Controller
running firmware version 1.7 or higher.
The CO
2
+ TRH sensor is not compatible with SE7000 Series Room Controllers.
Please note the sensor is available in two variations:
1. CO
2
+ TRH sensor (SED-CO2-G-5045)
2. TRH only sensor (SED-TRH-G-5045)
All information related herein applies to both models, except for CO2 functionalities which are only available on the CO2 + TRH sensor.
