5. Installation Guide
Follow these steps to correctly install your LED dimmer controller:
- Disconnect Power: Before making any connections, ensure that the power supply to your LED lighting system is completely disconnected.
- Identify Terminals: The dimmer controller has clearly labeled input and output terminals.
- INPUT (5-36VDC): Connect your DC power supply here. Observe polarity: '+' to '+' and '-' to '-'.
- OUTPUT: Connect your single color LED strip lights here. Observe polarity: '+' to '+' and '-' to '-'.
- Switch Push: Optional connection for an external push switch to control on/off and dimming.
- Wire Connections: Use appropriate gauge wires (0.5-2.5mm²) and ensure secure connections in the screw terminals. Strip approximately 6-7mm of insulation from the wire ends.
- Secure Installation: Place the dimmer controller in a suitable, dry location, away from direct heat or moisture.
- Reconnect Power: Once all connections are secure and verified, reconnect the power supply.

6. Operation
The JOYLIT LED Dimmer Controller can be operated using a compatible RF remote (V1 or RT6 series) or an external push switch.
6.1 Remote Control Operation (with V1 or RT6 Remote)
- On/Off: Press the power button on the remote to turn the lights on or off.
- Dimming: Use the brightness adjustment buttons or slider on the remote to increase or decrease the light intensity.
- Light On/Off Fade Time: The controller supports a selectable 3-second fade time for on/off transitions, providing a smooth lighting experience.
6.2 External Push Switch Operation
- Short Press: A short press of the external push switch will toggle the lights on or off.
- Long Press: A long press of the external push switch will initiate dimming. Release and press again to change dimming direction.
7. Pairing Instructions
To enable remote control functionality, the dimmer controller must be paired with a compatible RF remote.
7.1 Pairing with V1 Kit Remote (Auto Synchronization Transmitting)
The V1 kit remote allows for synchronized control of multiple dimmer controllers, ideal for large-scale applications. One remote can control an unlimited number of controllers within a 30M/98FT distance.
- Ensure the dimmer controller is powered on.
- On the dimmer controller, locate the 'MATCH' button.
- Press and hold the 'MATCH' button for approximately 3 seconds until the connected LED lights flash.
- Within 5 seconds, press the 'ON' button on your V1 remote. The LED lights will flash again, indicating successful pairing.
- For multiple controllers, the auto-transmitting function allows the signal to be relayed from one controller to another within 30M, ensuring synchronization across all paired units.

7.2 Pairing with RT6 Remote (Group Control)
The RT6 remote allows for group control, enabling you to manage different zones of lighting independently.
- Ensure the dimmer controller is powered on.
- On the dimmer controller, locate the 'MATCH' button.
- Press and hold the 'MATCH' button for approximately 3 seconds until the connected LED lights flash.
- Within 5 seconds, press the desired zone 'ON' button (e.g., Zone 1 ON) on your RT6 remote. The LED lights will flash again, indicating successful pairing to that specific zone.
- Repeat for other controllers and zones as needed.
