4. Product Overview
The ICC-510 consists of a main controller unit and a separate CO2 sensor module. The controller features a digital display and control buttons for easy operation, while the sensor provides accurate CO2 readings and includes a built-in photo sensor for intelligent light detection.


5. Setup
Follow these steps to set up your ICC-510 CO2 Controller:
- Mount the Controller: Choose a suitable location for the main controller unit. It can be hung using the integrated hook.
- Mount the CO2 Sensor: Place the CO2 sensor module in the area where CO2 levels need to be monitored. Ensure it is not obstructed and has good air circulation.
- Connect the CO2 Sensor: Plug the CO2 sensor cable into the designated port on the main controller unit.
- Connect CO2 Device: Plug your CO2 generator or regulator into the "CO2" outlet on the controller.
- Connect Ventilation Fan: Plug your ventilation fan into the "FAN" outlet on the controller.
- Power On: Plug the controller's power cord into a standard electrical outlet. The device will power on and begin monitoring.

6. Operating Modes
The ICC-510 offers three distinct operating modes to suit different environmental needs:
- Plant Mode with Fan: Designed for plant environments (e.g., greenhouses, grow tents) where high CO2 levels are beneficial during lighting periods. This mode utilizes both the CO2 device and a ventilation fan.
- Plant Mode without Fan: Similar to the above, but without active ventilation control. Suitable for environments where a fan is not required or controlled separately.
- Human Mode: Ideal for indoor spaces occupied by people (e.g., attics, basements). It monitors CO2 levels to ensure a healthy and comfortable living environment, activating ventilation when necessary.
Switch between modes using the control buttons on the device. The built-in photo sensor automatically detects day and night, enabling or disabling the CO2 outlet accordingly in plant modes.


7. Calibration
The ICC-510 offers two calibration methods to ensure accurate CO2 readings:
- General Calibration: A quick calibration method suitable for routine maintenance.
- Professional Calibration: A more precise calibration method for professional applications, ensuring optimal performance.
Refer to the on-screen prompts and the detailed instructions in the included user manual for specific steps on performing each calibration type.

8. CO2 Level Alarms
The controller features customizable high and low CO2 level alarms to alert you to abnormal concentrations. This ensures a safe and appropriate environment for both plants and humans.
- Setting Alarm Thresholds: Use the control buttons to set your desired high (AH) and low (AL) CO2 alarm thresholds.
- Alarm Indication: If the CO2 level exceeds the high threshold or falls below the low threshold, the device will trigger an audible alarm and display the corresponding alarm indicator (AH or AL).
- Alarm On/Off: The alarm function can be enabled or disabled as needed.

10. Troubleshooting
If you encounter issues with your ICC-510, try the following:
- No Power: Check if the power cord is securely plugged into both the controller and the wall outlet. Ensure the outlet is functional.
- Inaccurate CO2 Readings: Perform a calibration (General or Professional). Ensure the sensor is not obstructed and is placed in an area with good air circulation.
- CO2 Device Not Activating: Verify that the CO2 device is properly plugged into the "CO2" outlet and that the operating mode and set points are correctly configured. Check the photo sensor if in plant mode.
- Fan Not Activating: Ensure the fan is properly plugged into the "FAN" outlet and that the operating mode and set points are correctly configured.
- Alarm Constantly Triggering: Review your high and low CO2 alarm thresholds. Adjust them if they are too sensitive for your environment.
11. User Tips
- For optimal CO2 monitoring, place the CO2 sensor at plant canopy level in grow environments, or at breathing height in human-occupied spaces.
- Regularly check the sensor for dust or debris and clean gently to maintain accuracy.
- When using in plant modes, ensure the photo sensor is exposed to the ambient light conditions of your grow area for accurate day/night detection.
