ACCESSORIES INSTALLATION
CO2, Temperature, and Humidity / Temperature and Humidity Sensor Interface
The sensor is deployed by setting the interface with a push button and a multi-color LED. Both are hidden under the sensor housing and intended for use by a trained installer only (Figure 44).
Figure 44: Sensor Interface

MultiSITE CRC 2 Controller

Multi-color LED

Push button hole
Push Button The push button can be pressed through a hole from the bottom side of the sensor, with a slim tool . Each recorded button press is signaled by 2 yellow LED flashes.

· Short push
One 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 5-minute timeout interval.

· Long push
One 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.

Multicolor LED
The multicolor LED is hidden under the top plastic cover, positioned on left (Figure 44). In normal state the LED is off in order to conserve battery life. It is only used to signal the following special events: The LED flashes are 1/2 second.

· 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.

·
40

3 RED flashes signal a commissioning procedure failure. The sensor stays in decommissioned / hibernation mode.

Installation Manual

ACCESSORIES INSTALLATION
· 3 GREEN flashes signal a commissioning procedure success. The sensor will enter demo mode for 5 minutes. 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 acknowledgment command to the sensor after the sensor data report frames.
CO2 Autosensor Calibration
The 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 autocalibration period. For example, many buildings will drop quickly to background CO2 levels when unoccupied overnight or on weekends. The autocalibration function uses the information gathered during these periods to recalibrate.
The autocalibration 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 Setting The CO2 sensor is shipped with the autocalibration 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 autocalibrations in 8-day intervals.
It is normal for the sensor to display invalid readings during the first day following the initial installation and autocalibration. Minimum of 2 autocalibrations are required for accurate readings.
