Allure EC-Smart-Air Sensor with a CO2 Sensor
The Allure EC-Smart-Air Series sensors equipped with a CO
When these sensors are used in locations where the elevation is greater than 150 m (500 ft) above sea level, you need to set the Elevation input of the
sensor block in EC- gfx Program to the current location's elevation to obtain the most accurate readings.
For more information, refer to the sensor block section in the EC- gfx Program User Guide.
Under normal conditions, an Allure EC-Smart-Air sensor with CO
continuous operation provided that it was exposed to ambient air reference levels of 400 ppm ±10 ppm CO
The sensor will maintain accuracy specifications using the automatic self-calibration, assuming that it is exposed to the
atmospheric CO
concentration of 400ppm for at least 15 minutes per 7-day period, which is typically seen during unoccupied
2
periods.
Supported Quantity
The Allure EC-Smart-Air sensor connects to the controller's Subnet Port. Other devices may also be connected to this port in a daisy-chained fashion
(see the controller's datasheet for compatibility information and supported quantities).
Each controller supports a specific maximum number of Allure EC-Smart-Air sensors. The Subnet ID of all Allure EC-Smart-Air sensors must be set
within the indicated addressing range.
The Allure EC-Smart-Comfort Series and Allure EC-Smart-Air Series sensors share the same Subnet ID range: the same address
CANNOT be concurrently assigned to an Allure EC-Smart-Comfort Series sensor AND to an Allure EC-Smart-Air Series sensor.
