4. Operating the Controller
The NICREW Controller features three buttons for managing your aquarium light's functions. While specific button functions may vary slightly by light model, the general operation is as follows:
4.1 Basic Controls
- Power Button: Typically used to turn the light ON or OFF. A short press usually toggles power.
- Mode/Function Button: Used to cycle through different lighting modes (e.g., full spectrum, blue only, custom settings) or to enter programming mode for timer settings. A short press usually changes modes.
- Brightness/Adjust Button: Used to increase or decrease light intensity, or to adjust values within a programming mode. This button might have a dual function (e.g., short press for brightness, long press for timer adjustment).
Refer to your specific NICREW G2 or HyperReef 30W light manual for detailed instructions on programming advanced features like timers or custom light cycles, as the controller acts as an interface for these functions.
