Take full control of your Meridian lights with the Meridian Manual Controller, offering simple, direct operation without the need for an app or wireless network. Plug it into the dedicated port on top of your Meridian and enjoy customizable lighting with ease.

Key Features:

• Built-In Timer Options: Choose from 8, 10, or 12-hour programs, complete with a moonlight setting for overnight illumination.
• Adjustable Intensity & Color: Fine-tune your lighting with two intuitive knobs—one for white LEDs and the other for blue and violet LEDs.
• Seamless Modes: A single button on the controller provides access to four versatile modes:
  1. App Control: Disables manual settings, allowing full app-based operation.
  2. Manual Control: Runs lights continuously based on the current knob settings. If the power is interrupted, the controller remembers your settings and restores them when power returns.
  3. Sunrise/Sunset Timer: Automatically ramps up over an hour for a natural sunrise, maintains your set intensity during the day, and ramps down for a sunset effect. You can set an 8, 10, or 12 hour lighting cycle, which begins right after you set it.
  4. Sun & Moonlight Timer: During daylight hours, it fucntions the same as the Sunrise/Sunset timer. During night time, it adds a touch of realism with cool blues at 1% to emulate moonlight.
• Wall Mount: When not in use, the manual controller includes a wall mount to store it.

Whether you prefer manual adjustments or automated cycles, the Meridian Manual Controller provides a reliable, standalone solution to enhance your reef tank lighting experience.
