2CO2 + TRH Sensor Installation GuideSchneider Electric | II-CO2-Wireless-Device-028-6120-00 www.schneider-electric.com/buildings May 2017IntroductionDescriptionThe wireless CO2 + 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 - CO2 concentration. The measured data is communicated wirelessly using ZigBee Green Power protocol to a Room/ Zone controller.The sensor integrates an ultra-low power CO2 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.Box ContentsThe wireless CO2 + TRH sensor box contains the following:• Wireless CO2 + TRH sensor or TRH sensor• Wall-mounting bracket• Two screws for wall-mounting bracket• Installation guideSystem RequirementsIf used in conjunction with a Schneider Electric Room Controller, the wireless CO2 + TRH sensor requires a SE8000 Series Room Controller running ﬁrmware version 1.7 or higher.The CO2 + TRH sensor is not compatible with SE7000 Series Room Controllers.Please note the sensor is available in two variations:1.

6CO2 + TRH Sensor Installation GuideSchneider Electric | II-CO2-Wireless-Device-028-6120-00 www.schneider-electric.com/buildings May 2017Refer to the information below for detailed sensor operating instructions.Push buttonThe push button can be pressed through a hole from the bottom side of the sensor, with a slim tool (Figure 4). Each recorded button press is signaled by 2 yellow LED ﬂashes.• Short pushOne short push starts the commissioning procedure if the sensor is in the decommissioned (energy saving / hibernation) mode. If the sensor is already commissioned, it will enter “demo mode” for a 5min timeout interval.• Long pushOne long push puts the sensor into decommissioned / hibernate mode. The long push is conﬁrmed by one red LED ﬂash roughly 1 second after 2 yellow LED push signaling ﬂashes. After a red LED signal, the button should be released in order to prevent another unintended short push detection.Multi-colour LEDThe multicolor LED is hidden under the top plastic cover, positioned on left (Figure 4). In normal state the LED is off in order to conserve battery life. It is only used to signal the following special events:• 2 YELLOW ﬂashes conﬁrm each button push taken into account by the sensor.• 1 RED ﬂash acknowledges a long push. The decommissioning procedure and a sensor reset will be executed, then the sensor will enter hibernation mode.• 3 RED ﬂashes signal a commissioning procedure failure. The sensor stays in decommissioned / hibernation mode.• 3 GREEN ﬂashes signal a commissioning procedure success. The sensor will enter demo mode for 5 min. This demo mode will automatically timeout after 5 minutes. The sensor then stays in commissioned mode, periodically transmitting the measured values to the receiver.• 1 GREEN ﬂash acknowledges a valid GP command received by the sensor in demo mode. This feature can be used as a feedback to an installer to conﬁrm that the sensor is still in range during the commissioning (it works only in demo mode). In this case the receiver has to be programmed to send an acknowledgement command to the sensor after the sensor data report frames.The multiple LED ashes are executed only in 1/2 second intervals.Factory ModeThe wireless CO2 + TRH sensor is in a deep sleep mode waiting for a button push. No measurements, no radio communications are preformed. Operating ModesCommissioningDuring commissioning the wireless CO2 + TRH sensor will automatically ﬁnd and pair with the nearest compatible ZigBee Green Power receiver. ZigBee parameters (e.g. operational channel, Src-ID, PAN-ID, security level and key) are exchanged between the sensor and receiver in order to establish a reliable and secure link. During commissioning the sensor is presented as an UNSPECIFIED DEVICE (GP ModelID = 0xFE) with the GP Product ID = 17305 (0x4399) and its unique source ID (SrcID). The SrcID of each sensor is marked on its backside (Figure 5). The receiver should be ZigBee 3.0 compliant. The commissioning procedure can be triggered only from the Decommissioned / Hibernation Mode by a long push of the button. The commissioning procedure can be resumed through the following steps:1. Set a ZigBee operational channel (11 - 26) and the PAN-ID of your network (0xFFFF by default) on your ZigBee 3.0 compliant receiver.2. Put the receiver into the automatic commissioning mode (opened for the commissioning and accepting the commissioning with GP ModelID = 0xFE and GP Product ID = 17305 devices).3. On the wireless CO2 + TRH sensor press the push button once to start the bidirectional ZGP commissioning. The button actuating is immediately conﬁrmed by two yellow LED pulses. The sensor then automatically scans all ZigBee channels (channel 11-26) in order to ﬁnd the nearest ZGP Proxy device (receiver in commissioning mode) and initiates the pairing.4. Wait approximately 10s – during this time the sensor automatically performs the commissioning. The LED will not ﬂash during this period (even if you push the button again).5. Commissioning success is indicated by 3 green LED pulses. You can check measured data reported from the sensor to the receiver. If the commissioning fails (indicated by 3 red LED pulses) please ensure the sensor is in Factory Mode and in proximity of the receiver, then repeat the procedure.

Schneider Electric | II-CO2-Wireless-Device-028-6120-00 www.schneider-electric.com/buildings May 20177CO2 + TRH Sensor Installation GuideCO2 Sensor AutocalibrationPrinciple of operationThe CO2 module inside the wireless CO2 + TRH sensor, is fully calibrated prior to shipping from the factory. Over time, the measurement offset needs to be calibrated to maintain the long term stability of the sensor. In most applications, this can happen automatically using the built in auto-calibration function. This technique can be used in situations in which sensors will be exposed to typical background levels (400-450ppm) at least once during the auto-calibration period. For example, many buildings will drop quickly to background CO2 levels when unoccupied overnight or at weekends. The auto-calibration function uses the information gathered at these periods to recalibrate.The auto-calibration function uses the lowest point of CO2 concentration to recalibrate the offset. During every measurement cycle, the CO2 sensor stores the latest values, and also the lowest value recorded since the last calibration point.The ﬁrst 50 measurements after calibration are ignored when calculating the lowest value.Autocalibration default settingThe CO2 sensor is shipped with the auto-calibration feature enabled. There isn’t any CO2 measurement in the Factory Mode before the Commissioning. After the Commissioning all previous CO2 measurement data stored in the sensor is erased.By default the ﬁrst autocalibration will happen 1 day after the commissioning, and the following auto-calibrations in 8-day intervals.Demo ModeThe data measurement and TX period is temporarily reduced to 5 seconds. The green LED ﬂashes once after each valid ZGP command reception by the sensor. This feature can be used as a feedback to an installer conﬁrming that the sensor is still in the radio range of the receiver. Remember the sensor can receive a ZGP command only after a measured values report, so maximum green LED ﬂashing rate is 5s. The receiver has to be programmed to send an acknowledgment command to the sensor. The sensor automatically switches to Commissioned Mode once the 5min timeout elapses.Normal ModeThe sensor periodically measures T, rH and CO2 and reports the measured values to the receiver which it is paired with. By default the nominal measurement and Transmission(TX) period is 150s (2min and 30sec). This parameter can be edited by a ZigBee command. The sensor is always sleeping in between two data measurements and TX. It can be woken up at any time with the push button.When the CO2 concentration drops below the customizable comfort value the transmission period is multiplied by 4. The sensor automatically returns back to nominal transmission period if the CO2 concentration value exceeds the comfort threshold value.This device complies with Part 15 of the FCC Rules.
