Installation & Wiring Instructions
- Install the connections facing down to reduce the risk of water permeating the enclosures.
- For indoor installation only. Enclosures are not waterproof.
- Disconnect power from all devices before connecting or disconnecting cables to prevent damage to components.
The quadLINK is to be securely installed to a vertical wall surface using the mounting bracket provided.
Mounting the Enclosure
When possible, mount equipment outside of the growing environment for better service access and reduced exposure to humidity. If a quadLINK is to be installed in a humid growing environment, mounting in a sealed enclosure is recommended.
Follow these tips for best results:
- Install the quadLINK in a dry location away from drips or condensation.
- Ensure the quadLINK is accessible for service.
- Use a weatherproof enclosure for high humidity conditions (>70% continuous.)
- Place the quadLINK 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.
Connections
The quadLINK requires a 120Vac power source from a 15A branch protected circuit. A built-in DC power supply operates the electronics in the quadLINK from the 120Vac input.
HUB Connection Port: RJ-45 connector port for power.
Power Inputs: 4 Independent Receptacles
Power LED: Green LED indicates the quadLINK has power from the HUB connection or Wi-Fi.
Power Cord
Fuse Replacement
Replace fuses only with the size and current rating as marked on the PCB. Never install fuses with a current rating greater than that marked on the PCB. Disconnect power before removing cover and replacing fuse. If a fuse has blown, then the loads are too high for the relay and should be moved to separate relay devices.
Mobile App Setup Guide
1) 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).
2) Download the Growlink app from the Apple App Store, or Google Play Store:
3) Go to portal2.growlink.com/signup or tap the ‘Sign Up’ button at the login page of the Growlink Mobile App to 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.
4) Open the Growlink Mobile App and login to your newly created and verified account: 
5) Tap the icon of three lines in the top-left of the Mobile App, then tap the Hardware button in the following menu:
6) One can add a controller to an existing room, or tap the ‘+Add’ button in the following page to add a new room to your account. This is the container that will hold the future controller registration:
7) If you are creating a new Room, provide a name for the Room, the Square Footage of the Room, and the Room Type, followed by tapping the 'Create’ Button to finish creating that room:
8) Once an existing room has been selected or a new room has been created, tap the ‘Continue’ button to begin registering the controller to your account:
9) Within the Add Hardware Wizard, tap the LINKS button in the following page:
10) Select the ‘Add Devices’ option to add the controller to the specified room:
11) Select the ‘quadLINK’ option in the following menu that populates:
12) If you’re registering your quadLINK as a standalone device, tap the ‘Add as a standalone Wi-Fi Device’ option. LINKS connected via WiFi can only connect to secured 2.4GHz networks and cannot connect to WiFi networks that are not secured with a password and/or 5GHz WiFi networks.
If you’re registering your quadLINK to a LINKS Hub, tap the ‘Add to a HUB’ option:
Further instructions on how to add equipment to an existing LINKS Hub can be found HERE.
If registering the quadLINK as a standalone controller, the app will then search for a nearby device in listening mode. Ensure your quadLINK is in listening mode by holding down the setup button for at least 3 seconds.
14) Once the quadLINK is paired to your phone, designate the network you wish to connect the quadLINK to and input the credentials for that network:
Once WiFi credentials have been provided, all that is left is to name the controller and tap the ‘Next’ button on the following screen. The Mobile app will then attempt to register the controller to your account and pass those credentials towards the controller.
15) Once the quadLINK has been detected, the app will populate outputs of the quadLINK, where you can then name the outputs, set the device types for those outputs, and register that configuration to your quadLINK:
Once the outputs have been named to your liking and any required fields for the module have been designated, one can tap the ‘Register Device’ button to push that configuration to your newly configured quadLINK.
16) Once successfully connected and configured, the following success message will display. Tap the ‘Add Equipment to this Controller’ to add more hardware to this controller, Tap the ‘Edit Controller Profile’ button to update the Controller Profile Settings, or tap the ‘Go to Room Dashboard’ button to view the dashboard for the newly connected controller:
Troubleshooting
Relays are not activating, no power LED on PCB
Ensure the relay input terminals have 120VAC and are correctly wired. A dimly lit red LED should illuminate when the circuit board has power. If there is 120VAC at the input terminals, check that the fuse is not damaged (see fuse replacement.)
Relays are clicking but no power to an outlet
Check the status LED to determine if AC power is reaching the line terminal of thereceptacle. The red LED is powered by AC voltage from the line voltage terminal of the receptacle and will only illuminate if voltage is passed through the relay to the terminal. If the status LED for the receptacle is on, check the equipment by bypassing the relay.
