A1-EA Series Sensor Instruction 01 Introduction RuntalAire® A1-EA is a series of wireless sensors, which need to connect with the RuntalAire® L-4-EA controller. It combines temperature and humidity sensors with PM2.5 sensor(A1-EA-PM2.5) or CO2 sensor(A1-EA-CO2). It is suitable for indoor environmental quality measurement. 02 Model Specification Name Model Build-in Sensors Communication PM2.5 Sensor A1-EA-PM2.5 Temperature Humidity,PM2.
03 Parameters Name Range Resolution Precision Temperature -10℃～50℃ 0.1℃ 1℃ Humidity 1～99%RH 1%RH 3%RH CO2 0~5000ppm 1ppm ±(75ppm+10% of reading） PM2.5 0～999 ug/m3 1ug/m³ ≤100μg/m³: ± 10μg/m³ >100μg/m³: ± 10% of reading 04 Indicator light PM2.
05 Technical parameters Power supply: Battery /USB 5V. Appearance size: 86mm*86mm. Appearance material: PC+ABS flame retardant. Working environment: no condensation at -10-50 ℃ and 5-90%RH. 06 Operation There is a button at the back of the RuntalAire® A1-EA sensor. Turn on the sensor:Press the button once. Turn off the sensor:Press the button for 6 seconds. On/off the indicator light: Press the button once as the sensor is running.
Back of the A1-EA 07 Connect to the Controller Please refer to“L-4-EA Controller Manual”for details. Before connection, please make sure the sensor is on.Set the controller to sensor connection module. Press S3 +S4 for 3 seconds, and the air quality icon (green leaf) in the middle of the controller screen will be blinking.
Press the button at the back of the sensors for 3 times until the indicator light is red and blinking. When the sensor is connected to the controller, the indicator light stops blinking and the air quality icon(green leaf) at the controller will be lighted all the time. 08 Charging When the sensor is connected to the USB cable, if the battery power is less than 100%, the sensor will be charged automatically. Then indicator light will blink every 10 seconds, and will stop blinking after charging.
9 Safety instructions Commissioning and maintenance must be carried out by certified technicians. During use, it should be kept away from heat sources,high pressure,and not in contact with water.To charge the sensor, please use a 5V charger. It is strictly forbidden to directly connect to high voltage, high current charging,which will flow through the battery and damage it or make the battery heat, smoke, deform or burn. When not in use for a long time, please store the sensor well.
