4. Setup

4.1 Mounting the Controller and Sensor

1. Choose a suitable location for the main controller unit, ensuring it is easily accessible for viewing and adjustments.
2. Mount the controller using the provided screws or tapes.
3. Position the remote NDIR CO2 sensor in the area where CO2 levels need to be monitored. Ensure it is not obstructed and has good air circulation. The 14.8 feet (4.5 m) cable allows for flexible placement.
4. Connect the remote sensor cable to the main controller unit.
5. Plug the controller's power adapter into a standard AC outlet (AC100~240VAC).

4.2 Initial Calibration (Altitude Adjustment)

The controller supports altitude adjustment for accurate readings. If operating at a significant altitude, adjust this setting:

1. Access the menu on the controller.
2. Navigate to the altitude setting.
3. Adjust the altitude from 50 to 500 meters (164 to 1640 feet) as required for your location.
4. Confirm the setting to save.

5. Operating Instructions

5.1 Power On and Warm-up

After connecting the power, the device will perform a 30-second warm-up. During this time, the display will show a countdown or similar indication. Once warm-up is complete, it will begin displaying current CO2 readings.

5.2 Understanding the Display

The wide LCD screen displays real-time CO2 concentration, maximum and minimum recorded values, and a trend chart. It also shows the set target CO2 levels (Center and Zone).

5.3 Setting Operating Modes (Plant Mode / Human Mode)

The controller features two primary operating modes:

• Plant Mode: Designed for environments like grow rooms or greenhouses where CO2 enrichment is desired. In this mode, the controller activates a connected CO2 generator when levels fall below the set target.
• Human Mode: Intended for indoor spaces like offices or homes to maintain healthy air quality. In this mode, the controller activates a ventilation system when CO2 levels exceed the set target.

To switch between modes:

1. Press the 'Menu' button to enter the settings.
2. Navigate to the 'Mode' option.
3. Select either 'Plant Mode' or 'Human Mode' using the arrow buttons.
4. Press 'Enter' to confirm your selection.

5.4 Setting CO2 Target Levels (Center and Zone)

The controller uses 'Center' and 'Zone' values to define the desired CO2 range and control output.

• Center: The ideal CO2 concentration you wish to maintain.
• Zone: The acceptable deviation from the Center value. The controller will activate/deactivate output when CO2 levels move outside the (Center +/- Zone/2) range.

To set these values:

1. Press the 'Menu' button.
2. Navigate to 'Set Center' and 'Set Zone' options.
3. Use the arrow buttons to adjust the values.
4. Press 'Enter' to save each setting.

5.4.1 Output Control in Plant Mode

In Plant Mode, the controller activates the connected CO2 generator when the CO2 reading falls below the lower threshold and deactivates it when it rises above the upper threshold.

• Output Power ON: When CO2 reading < (Set Center - (1/2) x Set Zone)
• Output Power OFF: When CO2 reading > (Set Center + (1/2) x Set Zone)

Example: If Set Center = 1200 ppm and Set Zone = 400 ppm:

• Output Power ON (Activate CO2 generator/regulator) when CO2 reading ≤ 1000 ppm (1200 - (1/2) * 400).
• Output Power OFF (Shut off CO2 generator/regulator) when CO2 reading ≥ 1400 ppm (1200 + (1/2) * 400).

5.4.2 Output Control in Human Mode

In Human Mode, the controller activates the connected ventilation fan when the CO2 reading exceeds the upper threshold and deactivates it when it falls below the lower threshold.

• Output Power OFF: When CO2 reading < (Set Center - (1/2) x Set Zone)
• Output Power ON: When CO2 reading > (Set Center + (1/2) x Set Zone)

Example: If Set Center = 1200 ppm and Set Zone = 400 ppm:

• Output Power OFF (Shut off Ventilation fan) when CO2 reading ≤ 1000 ppm (1200 - (1/2) * 400).
• Output Power ON (Activate Ventilation fan) when CO2 reading ≥ 1400 ppm (1200 + (1/2) * 400).

5.5 Audible Alarm

The controller features an audible alarm that activates when the CO2 level exceeds a user-defined threshold. This threshold can be adjusted in the menu settings.

1. Press the 'Menu' button.
2. Navigate to the 'Alarm Threshold' setting.
3. Adjust the CO2 ppm threshold using the arrow buttons.
4. Press 'Enter' to save.

5.6 Auto Day & Night Detection

The remote sensor includes a photocell for automatic day and night detection. This feature allows the controller to automatically turn off the CO2 generator/regulator (in Plant Mode) or adjust ventilation (in Human Mode) by turning off the output power during the night, conserving energy and preventing unnecessary operation.

6. Maintenance

To ensure the longevity and accuracy of your DANOPLUS CO2 Controller, follow these maintenance guidelines:

• Cleaning: Regularly wipe the main unit and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Sensor Care: Keep the NDIR CO2 sensor free from dust and debris. Avoid exposing it to direct water spray or high humidity conditions beyond its operating range.
• Environmental Conditions: Operate the device within the specified operating conditions (0~50°C, 5-95% RH, non-condensing) to prevent damage.
• Storage: When not in use for extended periods, store the controller in a cool, dry place within the specified storage conditions (-20~60°C, 5-95% RH, non-condensing).
