3. Wiring and System Operation Instructions

(1) Water Supply System

Wire Selection: "Black" + "Blue" wires

Working Logic: When the float is at the low water level, the contact is closed; when the float rises to the high water level, the contact is open.

(2) Drainage System

Wire Selection: "Black" + "Brown" wires

Working Logic: When the float is at the high water level, the contact is closed; when the float drops to the low water level, the contact is open.

(3) Wiring Mnemonics and Principles

"Blue - Black": Closed at Low Position, Open at High Position

When the float head is downward, the power is connected to start the water pump. The rising water level of the water tank drives the float to rise. When the float head is upward, the internal steel ball falls, the power is disconnected, and the water pump stops. After water is used, the float head falls back downward, and the power connection cycles.

"Brown - Black": Closed at High Position, Open at Low Position

When the float head is upward, the power is connected to start the motor. The falling water level of the water tank drives the float to sink. When the float head is downward, the power is connected, and the water pump stops. After water is injected and the water level rises, the float head floats upward, and the power connection cycles.
