✅Working Description

The IT480WLC is a fully automatic water level controller with built-in water level indicator functionality. It is designed for single overhead tanks and operates in three modes using a 3-way rocker switch.
  Automatic Mode (Switch UP)

    Motor automatically turns ON when water level falls below 25% (Low-Level Sensor).

    Motor automatically turns OFF when water level reaches 100% (High-Level Sensor).

    All 4 level indicators remain functional.

   OFF Mode (Switch CENTER)

    Motor remains OFF regardless of water level.

    Water level indicators continue to display tank levels.

   Manual Mode (Switch DOWN)

    Motor remains ON continuously, regardless of sensor inputs.

    LED water level indicators remain active.

    Used when you want to manually fill the tank.

✅Motor Control Compatibility

    Supported: Direct ON/OFF via switch or MCB, electronic starters

    Not Supported: Push-button starter panels

✅LED Indications

    25% – Low Level

    50% – Mid Level

    75% – High-Mid Level

    100% – Tank Full (Triggers Auto-OFF in Auto mode)

    Motor ON Indicator – Shows when motor is active

⚠️ Important Notes

    This model is only for overhead tanks and does not support dry run protection.

    Ensure proper wiring of the reference sensor (G) for accurate sensing.

    Sensor tips must be clean and submerged properly.

    Use only MCB or switch-based motor starters, not push-button-based.
