How to Control & Use This Controller

1. Wiring: Ensure the power is off. Connect your DC power supply (5-24V) to the 'INPUT' V+ and V- terminals. Connect your single-color LED strip to the 'OUTPUT' V+ and V- terminals, observing correct polarity.
2. Pairing: Power on the VK receiver. Briefly press the 'Learning Key' on the receiver. Then, immediately press the desired zone or control key on your L-Tech RF remote or EX touch panel.
3. Confirmation: The connected LED strip will flash once to confirm that the pairing was successful.
4. Control: You can now use the paired remote or panel to turn the lights on/off and adjust the brightness wirelessly.

⚠ Precautions

Always use a power supply with a voltage that matches your LED strip (e.g., a 12V power supply for a 12V strip).
Do not exceed the maximum power or current rating of the controller. Calculate the total load of your LED strip before connecting.
Ensure proper ventilation around the controller to dissipate heat and maintain performance.
The effective control distance may be reduced by walls, metal obstructions, or other sources of RF interference.

Frequently Asked Questions

Q: What is the function of the VK controller?

A:The VK is an RF receiving controller. It receives a wireless signal from a compatible L-Tech remote or wall panel (like the EX series) to control the brightness of single-color LED strips.

Q: Can I use this controller by itself?

A:No, the VK receiver requires a compatible L-Tech RF transmitter (remote control or touch panel) to function. It cannot be controlled directly via WiFi or a mobile app on its own.

Q: How do I pair the VK with my remote control?

A:Simply press the 'Learning Key' on the VK controller, then immediately press the desired key or zone on your remote. The connected lights will flash to confirm a successful link.

Q: Can I control multiple separate LED strips with one remote?

A:Yes. You can pair multiple VK receivers to the same zone on a remote to control them together, or pair different receivers to different zones for individual control.

Q: What type of LED strip is this controller for?

A:This is a single-channel controller designed for constant voltage, single-color (monochromatic) LED strips, such as those in warm white, cool white, red, green, or blue.

Q: Will this work with RGB, RGBW, or Tunable White (CCT) LED strips?

A:No, the VK is a single-channel model for dimming only. For multi-color or CCT strips, you need a corresponding multi-channel L-Tech receiver.
