Installation & Wiring Instructions
Mounting the Enclosure
When possible, mount equipment outside of the growing environment for better service access and reduced exposure to humidity. If a batch tankLINK is to be installed in a humid growing environment, mounting in a sealed enclosure is recommended.
Follow these tips for best results:
- Install the batch tankLINK in a dry location away from drips or condensation.
- Ensure the batch tankLINK is accessible for service.
- Place the batch tankLINK in the area intended for mounting. Ensure there is adequate space for connections.
- Mark the hole locations and install anchors or pre-drill holes if necessary.
- Mount the enclosure to the wall or ceiling using mounting bracket.
Note: Protect input jacks from dust or contamination during installation, cover ports with masking tape.
Connections
The batch tankLINK must be connected to a Growlink HUB, or to your WI-FI network as a stand-alone controller. The batch tankLINK offers inputs for EC, pH, and temperature probes, as well as a level sensor.
Power Supply: 24VDC / 1 Amp power supply is required to operate the HUB.
Hub Connection Port: Connect HUB connection devices to the numbered hub ports. All cabling is standard 8-conductor RJ-45 straight through (no cross-over.) T568B pattern recommended.
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.
- Go to Growlink.com/signup and create a Growlink Account:
- After creating your account, a verification email will be sent from ‘no-reply@growlink.com’ to the email address set for your newly created account. One must verify your email address in order to utilize your newly created account.
- Open the Growlink Mobile App and login to your newly created and verified account:
- Once logged in, tap on the settings icon in the top right corner and then tap Add New Hardware.
NOTE: The first time using the Growlink app you will be prompted to allow Bluetooth access. This is required to set up newer Growlink controllers.
- Select the ‘Add a New Controller’ option in the following menu if you’re connecting a new Links Hub to your account:
- Selecting this option will open the Controller registration wizard within the Growlink Mobile App. Follow the steps in the wizard to connect the LINKs HUB to your network via Wi-Fi or Ethernet:
- Once the controller has been registered to your account, you will be prompted to select a Room. If no Room exists, tab the button to ‘Create a new room’ at the bottom of the page:
- Once a new room has been created, you will be taken to the Profile page of the new room to edit any important settings, such as the desired time zone, day range, and lighting shutdown temperature failsafe. Once the room’s profile has been configured, tap the ‘Save and Add Devices’ button at the bottom to begin registering devices to your created room:
Note: The Lighting Shutdown Temperature failsafe is a failsafe that exists on every Growlink Controller. This failsafe will shut off any ‘Lights’ device if any recorded temperature reads above the specified value in order to protects the plants in the room. The lights will turn back on once the temperature has dropped below the value specified for at least 10 minutes.
Calibration
- Once you have your batch tankLINK registered and installed you can start to calibrate your sensors.
- First hit the menu button:
- Then navigate to Calibration menu using the middle button:
- Hit the ENT button to select the menu option and then navigate to the Temperature menu:
- Then navigate to Calibrate and hit ENT:
- Follow the on-screen directions once inside of this menu.
- Adjust is for adding an offset to displayed value if you feel the reading needs adjustment.
- Accept the calibration by pressing YES (far left button):
- Once you have finished calculating your Temperature Probe select pH:
- Select Calibrate:
- Follow the Direction on Screen and click NEXT:
- After completing the pH calibration, you can move on to EC:
- Select Calibrate:
- Follow the directions on the screen and click NEXT:
- Wait for the readings to stabilize and click DNE:
- If you puchased a level sensor you final step will be to calibrate it. Scroll down to Next in the Calibration menu:
- Select Depth:
- Then Select Calibrate:
- Follow the Directions on Screen and click Next:
- Make minor adjustments to the level once calibrated (if needed) and hit ENT to save.
- Click YES to finish the calibration if everything looks correct.
- All Aspects of your batch tankLINK are now configured.
Troubleshooting
Controller not showing up on my list of devices to connect:
Check your phone or tablet and ensure Bluetooth is enabled.
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. Then refresh the device list on your phone or tablet.
Unplug the unit for 10 seconds and then plug the device back in and wait for the LED lights to stop changing colors (typically 15 seconds). Then refresh the device list on your phone or tablet.
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.
