The In-Wall RGBW LED Controller is our most stylish RGBW LED controller. This permanently mounted in-wall controller allows you to control your RGBW LED fixtures, providing full color and brightness control. Simply connect this unit to its receiver (or control box), your RGBW LED fixtures and a power supply, mount your wall plate, and start controlling your fixture. Choose any color output using the touch wheel and easily turn your dedicated white chips on and off. This RGBW LED controller is compatible with all of aspectLEDs RGBW LED fixtures. Please note, this remote controller requires a base unit available here. This in-wall controller communicates with its receiver wirelessly, but must be hardwired with low voltage wire to your power supply. To pair this controller with its base unit, turn the in-wall unit on, then the desired zone number on the remote (1-3). Press the learning key on the base unit, then touch the color wheel. Your lights should blink, and your controller should be paired.
