Push Button Functions:
- First Press: Activates feed mode for 10 minutes. The RED light will illuminate.
- Second Press: Extends feed mode to 30 minutes. The GREEN light turns on.
- Third Press: Further extends feed mode to 50 minutes, indicated by the BLUE light.
- Fourth Press: Exits feed mode and returns to normal operation.
Note: When exiting feed mode and returning to normal operation, the system automatically reduces the pump speed by two levels for one hour as a precaution to prevent overflows and ensure aquarium stability. For example, if the default speed is 8, it will temporarily drop to 6 upon exiting feed mode, then return to 8 after one hour. You can disable this feature using the steps below if desired.
