Controller and Sensor Dimensions
Installation & Wiring Instructions
If installing Batch Tank Monitors in a commercial facility with a Growlink Nutrient Delivery System, do not terminate level sensor cable on BTM 4-20mA Input. All level sensors need to terminate at the system control panel. Refer to panel drawings for exact terminations.
*Note: The PT1000 temp sensor's wires can be connected to the Temp input terminal block in any order, as polarity does not matter.
Mobile App Setup Guide
- Plug in your Growlink device to power it on. The LED should be blinking blue. If not, hold the SETUP button until status light flashes blue rapidly (12-15 seconds).
- Download the Growlink app from the Apple App Store, or Google Play Store.
- Open the Growlink app and tap Create Account.
- After creating an account, log into the app.
- Tap on the settings icon in the top right corner and then tap Connect a Controller. If it is your first time creating an account, you will be automatically prompted to Setup A New Device.
NOTE: The first time using the Growlink app you will be prompted to allow Bluetooth access. This is required to setup newer Growlink controllers.
- Connect the controller to internet. Watch the video or follow the instructions below to learn how.
- For iPhone users:
- If controller has a Bluetooth logo printed on it, tap New Bluetooth Device, then tap on the controller you wish to connect to from the list. A successful connection will be indicated with a "Congrats" message.
- If using a Legacy model controller (Non-Bluetooth), tap "Legacy Wi-Fi Device". From the "Waiting for Wi-Fi connection" screen, follow the instructions shown on your device to complete the Wi-Fi connection process.
- For Android users: The Growlink app will detect if your controller is a Bluetooth device or a Legacy model device. Simply tap on the controller you wish to connect to once it shows on the screen.
- For iPhone users:
- After the connection process is complete, a list of available Wi-Fi networks will appear. Tap on the network you wish to connect the controller to, enter the network password, then tap Next.
- Name your controller (i.e. Flower Room Irrigation). Tap Register Controller.
- After controller registration, tap on Go To Settings.
From the Controller Profile page, you can set where you are located, time zone, Day Start & Day End (Lights On and Lights Off). After making changes, tap Save and you will be returned to the Main Dashboard.
pH & EC/TDS Calibration Process
Note: The Batch Tank Module uses the same calibration process as the Growlink SW-2. View the video below to see the process. Mention of the pH #2 input only applies to the SW-2.
Troubleshooting
Controller didn’t connect to Wi-Fi:
If unsuccessful in the first attempt to connect the controller to the Wi-Fi network, hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Once rapid flashing becomes visible, immediately release the Setup button. This will put the controller into Listening Mode (Blinking Blue). Now, restart the connection process outlined in the Quick Setup Guide section above.
The Wi-Fi network being used has changed:
In the event the controller needs to re-connect to an existing or new Wi-Fi network, put the controller back into Listening Mode (see above) and follow the Controller Connection process outlined in the Quick Setup Guide section above.
pH values are not as expected or do not match with 3rd party measuring device:
Recalibrate pH and EC Probes (see video above). To ensure accuracy, recalibrate 3rd party measuring device using the same buffer solutions used to calibrate the Smart Water Wireless 2/ Batch Tank Module probes.
