5. Setup and Installation
5.1 Pre-installation Checks
- Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz Wi-Fi.
- Confirm your garage door opener has a low-voltage input for a wall button or similar control.
- Have your Wi-Fi network name and password ready.
5.2 Wiring the Controller
- Disconnect Power: Turn off the power to your garage door opener at the circuit breaker.
- Connect to Opener: Connect the two output wires from the GONLEN controller to the terminals on your garage door opener that are typically used for the wall button. These are usually labeled 'Push Button', 'PB', 'Wall Control', or similar. The polarity typically does not matter for these terminals.
- Connect Sensor: Plug the magnetic door sensor cable into the 'NO Sensor' port on the GONLEN controller.
- Connect Power: Plug the power adapter into the controller and then into a power outlet.
5.3 Installing the Door Sensor
The magnetic sensor consists of two parts: a main sensor unit and a magnet. These parts must be installed in close proximity to each other when the garage door is closed, and separate when the door is open.
- Mount the main sensor unit securely to the garage door frame or wall.
- Mount the magnet to the top panel of the garage door, directly adjacent to the main sensor unit when the door is closed. Ensure the gap between the sensor and magnet is minimal (typically less than 1 inch) when the door is closed.
- Use the provided screws or adhesive pads for secure mounting.
