3. Operation 3.1 Installation Mode ● ● ● Users need to press the button over 5 seconds to activate operation into installation mode. When the Sensor tries to join the network, it will keep blinking the yellow LED for 3 seconds. Once the sensor joins the network, the yellow LED will keep on for 3 seconds and send an uplink with a CO2 value of 0. Users can press the button for over 5 seconds to try to join the network again. 3.
