3. Setup Instructions
3.1 Physical Installation
- Mounting: Choose a suitable location to wall-mount the Bluelab Guardian Monitor. Use the provided mounting screws to secure the unit. Ensure it is easily accessible for viewing and probe connections.
- Probe Placement:
- Connect the Bluelab pH Probe and the Conductivity/Temperature Probe to the designated ports on the monitor.
- For standard reservoir monitoring, place the probes directly into your nutrient reservoir. Use the pH probe holder with a suction cup to secure the pH probe in place.
- For inline systems, ensure probes are fixed directly in line with your fertigation system (for inline models).
- Power Connection: Connect the 5V DC power supply to the monitor and plug it into a suitable 110-240 VAC outlet using the appropriate interchangeable plug adapter.

4. Operating Instructions
4.1 Real-time Monitoring
The Bluelab Guardian Monitor provides continuous, real-time readings for three critical parameters:
- Conductivity: Displays in EC/CF, TDS (ppm 500), and ppm 700 scales. Press the "Units" button next to the Conductivity display to cycle through the units.
- Temperature: Displays in °C or °F. Press the "Units" button next to the Temperature display to switch between Celsius and Fahrenheit.
- pH: Provides accurate pH measurements.

4.2 Setting Alarms
You can set high and low alarm points for pH, temperature, and conductivity to ensure your growing environment stays within optimal ranges. If a parameter falls outside the set range, the monitor will flash a visual alarm, and you will receive instant notifications via the Edenic app.
- On Device: Use the arrow buttons on the monitor to navigate to the alarm settings for each parameter and adjust the high/low thresholds.
- Via Edenic App: Access the device settings within the Edenic app to set and manage alarm ranges remotely.

4.3 Remote Monitoring and Data Logging
The Edenic by Bluelab app provides comprehensive remote access to your Guardian Monitor:
- View current readings for all parameters.
- Receive instant alerts on your smartphone if parameters deviate from set ranges.
- Access historical data and trend reports to analyze your growing environment over time and make informed decisions.
5. Calibration
Regular calibration of your pH and conductivity probes is essential for maintaining accuracy and ensuring optimal performance of your Bluelab Guardian Monitor. Use fresh Bluelab calibration solutions for best results.
5.1 pH Probe Calibration
The pH probe requires a simple 2-point calibration process using pH 7.0 and pH 4.0 calibration solutions.
- Ensure your pH probe is clean and rinsed with RO water.
- Initiate pH calibration on the device (refer to the 'Getting Started Guide' for specific button presses).
- Place the pH probe into the pH 7.0 calibration solution. The device will automatically detect and calibrate to pH 7.0.
- Rinse the probe thoroughly with RO water.
- Place the pH probe into the pH 4.0 calibration solution. The device will automatically detect and calibrate to pH 4.0.
- Once both points are calibrated, the pH probe is ready for accurate measurements.

5.2 Conductivity Probe Calibration
The conductivity probe typically requires calibration with a known conductivity standard (e.g., 2.77 EC). Refer to your 'Getting Started Guide' for detailed instructions on conductivity calibration.
6. Maintenance
Proper maintenance extends the lifespan and accuracy of your Bluelab Guardian Monitor and its probes.
6.1 Probe Care
- Cleaning: Regularly clean probes to remove nutrient buildup. Use a soft brush and Bluelab Probe Cleaner.
- Storage: Always store the pH probe in Bluelab KCl Storage Solution when not in use to prevent the sensor from drying out.
- Replacement: The Bluelab pH Probe is replaceable. If accuracy degrades despite proper cleaning and calibration, replace the pH probe.

7. Troubleshooting
If you encounter issues with your Bluelab Guardian Monitor Wi-Fi, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate pH readings | Probe is dirty or dry; needs calibration; probe is old/damaged. | Clean and re-calibrate the pH probe. Ensure proper storage in KCl solution. If issues persist, replace the pH probe. |
| Monitor not connecting to Wi-Fi/App | Incorrect Wi-Fi password; device out of range; app issues. | Verify Wi-Fi password and network. Ensure the device is within Wi-Fi range. Restart the app and the monitor. Check for app updates. |
| No readings or erratic readings | Loose probe connection; damaged probe; power issue. | Check all probe connections. Inspect probes for visible damage. Ensure the power supply is stable. |
| Alarms not triggering or incorrect | Alarm settings incorrect; device not connected to app. | Review and adjust alarm thresholds on the device or in the Edenic app. Confirm app connectivity. |
